The Latest Versions of SQL Server, the OS
SQL Server may not always be the latest and greatest version available; to stay competitive, you should deploy as recent a version as possible - Microsoft strives to enhance their products through each release, improving efficiency and quality with every new release.
Please upgrade to the latest SQL Server version to take advantage of lesser-known features and enjoy extraordinary performance and productivity.
- SQL Server has added Windows functions and error messages, providing developers with more robust yet elegant code-writing methods.
- SQL Server includes an improved algorithm for creating Virtual Log Files. Many virtual logs may slow the writing transactions away; now, the default behavior provides better support.
- With this version, the number of latches needed for creating tempdb objects was dramatically decreased - an invaluable aid to applications traditionally limited by this system-shared resource.
- SQL Server Adaptive Query Processing--Microsoft intends to help your workload adapt over time by assigning more memory per query plan during subsequent runs; for example, if too little was assigned and data leaked onto disk during one attempt, more memory will be assigned on subsequent tries.
- SQL ServerTable Variable Compilation Deferred feature delays compilation statistics of Table Variables by first using row counts when queries are executed for optimizing downstream operations. This feature makes the data more manageable.
Step 7 will detail how you can increase transactional performance without adding extra hardware. When possible, always opt for the most recent version available.

Create Your Server
One cannot expect Ferrari-level performance from an old Fiat engine; your SQL Server should meet its intended purpose before being configured, deployed, or built. Take this opportunity to flex your soft skills by asking about their requirements - otherwise, you are unprepared and won't know which server works best!
Selecting an optimal SQL Server Edition becomes possible by understanding your business requirements (Developer or Enterprise editions, SaaS, etc). Enterprise features might be needed when considering these factors, while Developer features could save on licensing. When making this decision, it is wise to Popular Service carefully assess current and potential needs before selecting an SQL Server edition.
Depending on the server's use, its configuration can differ significantly between systems. regularly alter several aspects; before making changes or adjustments of this nature, it's wise to familiarize oneself thoroughly and test all settings involved before making decisions or changes - this could include things such as:
- Maximum Degrees of Parallelism
- Cost Thresholds for Parallelism
- Minimum / Maximum Server Memory
- Optimize Ad Hoc Workloads
- Remote Administration Connections
- Backup Compression by Default
Before SQL Server,may have modified some settings related. Watch "Investigating TempDB Like Sherlock Holmes", an on-demand webcast, to learn more.
Make Sure Your Server Can Handle The Expected Workload
Stress testing and soak testing the hardware you plan to deploy into a critical business environment is paramount. TPC Benchmark tests offer one such solution as an effective stress and soak testing Standard Tier technique. By running TPC benchmark tests, you can test hardware at its limits while pushing its potential even further - also helping identify any possible issues while pushing to its utmost potential and pushing to its limiting point; also helping establish where absolute limits differ significantly from theoretical ones if performed. If successful tests occur, you will see where physical limits differ significantly more significantly or vice versa by conducting similar stress/soaked tests yourself vs performing these stress and soak tests yourself!
Proper monitoring practices must be in place before moving on to this next step. You should set baselines to verify if changes made have an impact.
- This tool serves as a performance evaluation of the storage subsystem you currently utilize, which may not go over well if used by multiple systems that share this subsystem simultaneously. Make sure it runs from only your system before performing this exercise - restore and backup large databases to test throughput performance if applicable.
- HammerDB, an open-source load-testing application, makes configuration testing quick and straightforward by simulating multiple users simultaneously.
Select The Optimal Data Types azure analysis services developer
SQL Server is designed as an information retrieval and storage system at its core, so the way data is stored directly affects how fast retrieval takes place. So where exactly is information stored within SQL Server?
Pages store our data, each having an 8KB size limit. Each data type requires different amounts of space; choosing an optimal data type depends upon knowing its attributes and what each record should include. SQL Server uses fewer resources when reading dense data sets; performance tuning focuses on Network Asset efficiency.
Solve Blocking and Deadlocks
Locking data in multi-user systems is expected to maintain the consistency of its records, such as SQL Server's. When performing select operations, its default concurrency locks a row, page partition or object when performing its select operation - the lock prevents write operations from occurring (depending on Cloud Infrastructure where and at what level the lock was applied), while exclusive locks for writing prevent access by request of SELECT command (reverse effect of shared locks requested via SELECT command).
Blocking, or "live locking", stops readers and writers from communicating with each other; blocking can have severe ramifications on performance. To maximize concurrency, you should seek to limit blocking (or "live locking").
Read-committed concurrency is often known by another name - Pessimistic concurrent concurrency. SQL Server offers two concurrency modes that differ significantly: Pessimistic concurrency is for read Mobile Application committed while optimistic concurrency (Optimistic was default with Oracle) allows readers to continue working without being blocked by writers; when requests for changes arrive, they are stored temporarily in Version Store within Tempodb and this temporary data copy accessed by readers; although this method does have its drawbacks; any modifications should be thoroughly tested before being put live.
Indexing can help mitigate the adverse impacts of locking. We will explore what constitutes an effective indexing strategy in this section. Deadlock has long been seen as a side-effect of locking; unfortunately, it's often unpleasant and rarely produces satisfactory results when multiple queries attempt to lock two or more objects simultaneously.
You can follow the sequence of numbers to see what happened:
- A row in the table, Rainfall_Rates, for session 88 is locked.
- A row in the table is locked.
- A row in the table Rainfall_Rates is locked.
- A session locks a row in the table Consumption_Rates.
This scenario involved rolling back Session ID 88. For any deadlock situation to resolve successfully, either roll back the previous transaction or issue new attempts to ensure data are in their desired states.
There are various strategies available to you to resolve a deadlock situation. Refactored code may help avoid objects being accessed out-of-order, while traditional query tuning offers other avenues of resolution.
Optimize Indexes
An essential skill of every Microsoft Data Platform expert should be understanding indexing. You can learn more by reading Erin Stellato's two-part book "An Approach to Index Tuning," Parts and II.
Over time, have written extensively about indexes. Some experts consider indexing more art than science;agree that you need to find the balance between performance in both read/write operations and resource usage and management. Indexing does carry a cost; however, creating too many could affect their performance or waste storage space, causing insert/update/delete operations to become compromised or wasted space consumed by excess indexing efforts.
Plan Explorer, part of SQL Sentry query optimization and analysis tools, allows for effortless query analysis by quickly and effectively identifying which query attributes are utilized and should be covered by indexes. Figure 2 details why an index may be necessary and ways it may be modified to address scanning issues.
Adopt A Set-Based Mentality
Around one year ago, worked with a customer experiencing significant challenges with their data load. Utilizing SQL Sentry Top SQL, quickly identified all long-running SQL queries which needed attention.
Most users employ cursors to navigate records; in this instance, only one query was submitted, including a user-defined scalar function (UDF). That meant calling out this UDF against each row which met WHERE criteria in an execution plan - thus disclosing its actual cost to all involved.
Converting this UDF and SELECT statement into one that only fires once for each result set took me approximately 10 minutes, using SQL Server resources more efficiently and ensuring REPLACE statements and parenthesis lined up perfectly. Everybody has different quirks; though performance Azure Resource improvements may not always be possible, Aaron Bertrand offers excellent guidance in his blog on reducing cursor overhead.
Do Not Make Changes To Production
Avoiding all users from entering data through applications they use isn't necessarily best practice (although this might make sense in certain circumstances). It's more about cutting production change costs; Fixing problems during development rather than later production has proven true for me in practice.
All changes should be evaluated in at least another multi-user environment and, where relevant, using synthetic testing scenarios like those detailed earlier. You must be able to quantify and confirm their impacts before moving ahead with any change.
Make wise financial choices starting from the outset with Plan Explorer's index analysis features in mind. Avoid paying more later for errors arising from doing things incorrectly the first time. Use its index analysis features to optimize SQL queries before they enter production - saving yourself from an ordeal where attempting to search out those pesky killer queries could waste hours searching the databases alone for viable leads! Instead, work closely with developers and vendors so that as few killer queries as possible ever reach production environments.

Performance Tuning And Monitoring In Azure SQL Database Managed Instance
Start by keeping track of CPU and IO resource utilization relative to your database's performance by choosing an Azure SQL Managed Instance or Azure SQL Database service tier azure app service development or performance level and viewing their resource metrics, either through Azure portal or SQL Server management tools such as:
- Azure Data Studio and SQL Server Management Studio both utilize Visual Studio Code.
- Azure SQL Analytics preview is not suitable for solutions requiring low latency monitoring.
Azure Portal Database Advisors
Azure SQL Database offers various Database Advisors, which offer automatic performance optimization options and intelligent recommendations to maximize performance. Furthermore, its Query Performance Insights page details which queries account for most CPU and IO use across single databases and pools.
- The Azure portal offers an automatic Query Performance insight for Azure SQL Databases within its "Intelligent Performance" heading in its Overview pane, helping to optimize workload by recognizing queries. Use this data gathered automatically by optimizing workload and eliminating queries as soon as they appear in queries analyzed automatically by the Azure portal.
- Automatic tuning enables you to automatically implement recommendations. For instance, nonclustered index creation/drop may occur according to workload patterns. Azure Portal also features this service under the Intelligent Performance heading in their Overview pane for Azure SQL Databases.
- Azure SQL Managed Instance and Azure SQL database provide advanced monitoring and optimization features backed by artificial intelligence for optimal performance optimization and troubleshooting of solutions and databases, such as Intelligent Insights, that you can configure to stream to multiple destinations.
Azure SQL Database, SQL Managed Instance and Azure Portal do not possess all of the same monitoring and diagnostic tools found within their respective database engines - these include query stores and dynamic management views (DMVs) used for performance monitoring for scripts used for such monitoring, please see Monitoring with DMVs.
Azure SQL Insights (preview) and Azure SQL Analytics (preview)
These offerings present data in various ways for various endpoints.
- Azure SQL Insights is an initiative within Azure Monitor designed to give an in-depth view into Azure SQL database activity. Telegraf is the collection agent that collects and transports the collected data between SQL sources and Log Analytics for further processing and analytics.
- Azure SQL Analytics Preview requires Log Analytics to gain deeper insight into Azure SQL database activities.
- Azure Diagnostics Telemetry offers a live data stream separate from Azure SQL Database or Managed Instance. SQLInsights should not be confused with Azure SQL Insights preview; instead, it's part of Intelligent Insights as one package of Telemetry from the Diagnostic Settings feature that emits them - you may recall Resource Logs being known previously. Please see Diagnostic Telemetry Export for further details.
- Azure SQL Analytics preview utilizes resource logs generated from diagnostic telemetry settings on the Azure portal, while Insights preview provides its pipeline to collect Azure SQL Telemetry.
Telemetry For Monitoring And Diagnosis
This diagram depicts all Azure SQL product metrics and logs - such as Activity Logs and Resource logs - and how these logs are processed and surfaced for analysis.
Azure Sql Can Be Tuned And Monitored In The Azure Portal
Azure SQL Database, Azure Managed instance and Azure Portal all offer resource metrics monitoring capabilities for monitoring resource metrics such as resource metrics monitoring. Furthermore, Azure SQL Database offers database advisors to guide database administration, while Azure Performance Insight offers query optimization recommendations to optimize queries in performance queries. Query Performance Insight provides query optimization recommendations. Azure Portal automatically tunes logical SQL server databases or single or pooled SQL databases using query-tuning recommendations from iterations through iteration-tuning features.
Portals may display less usage than actual amounts for databases with shallow usage. Telemetry will not be as precise because double numbers are converted to integer numbers; specific usage values less than 0.5 are rounded down to 0. For further details, see Low database and elastic pools metrics rounding zero.
Azure SQL Database Resource Monitoring and Azure SQL Managed Instances
At Azure portal's Metrics Section, it's easy to monitor resource metrics quickly. By monitoring them, you can determine if your database's CPU, memory or storage is reaching its limits quickly; high DTU or CPU utilization could indicate you require more resources; conversely, it could suggest your queries aren't appropriately optimized if they remain high DTU/CPU utilization numbers; for details regarding supported Azure SQL Database metrics visit Microsoft. Sql/servers/databases; ElasticPools for elastic Pools; and Microsoft. SQL/managed instances, respectively
Database Advisors in Azure SQL Database
Azure SQL Database offers database advisors who offer performance tuning advice for individual databases or pools of databases, accessible via Azure Portal or PowerShell. The Azure SQL Database automatically applies these recommendations when automatic tuning is activated.
Azure SQL Database Query Performance Analysis
Query Performance Insight provides insight into the Azure portal performance of top-consuming and longest-running queries across single databases and pools, providing visibility into their cloud application development service consumption rates and durations.

Rounding Down To Zero, The Low Database And Elastic Pool Metrics
Beginning September 2023, databases with low usage may appear in the portal as having less usage than they have due to how telemetry data is created: double values converted to integers may result in some usage figures under 0.5 to be rounded down to 0, which causes loss of granularity and ultimately results in inaccurate reporting of actual usage figures.
As an illustration, consider a one-minute window that includes four data points of equal magnitude: 0, 0.1, 0, 0.1 and 0, 0. These low values were rounded to represent a mean of 0. The average value is calculated as 0.25 when any point exceeds 0.5; in such an instance, these four values would become 0.10.10.90.11.
Create Intelligent Performance Assessments
Intelligence Insights is an integrated feature designed to monitor database performance and detect Virtual Network disruptive events, including wait times for query execution, errors or timeouts that impact database performance issues. Intelligent Insights performs detailed analyses that result in the Azure Virtual Machines SQLInsights log resource; it does not correlate directly to Azure Monitor SQL Insights Preview but provides intelligent evaluation of issues and recommendations to enhance database performance.
