Overview on SQL Server Performance Tuning

SQL Server Performance Tuning is an important subject and it is essential to implement various measures in regular intervals of time to optimize the scalability and performance of the Server.
Several parameters that can be executed for stimulate Server performance are mentioned herein.

Server Level Configuration Check:

For tuning the Server performance to the maximum, it is required to review and check all the Configuration settings of the SQL Server on periodic basis.

Index Analysis:

To achieve better Server performance, it is important to create useful indexes. Proper indexing helps in executing tasks with minimal disk Input\ Output operations and fewer system resources.
To implement this approach, it is important to understand how indexes are used by ‘Query Processer’ for executing quick data search operation.

SQL Wait Stat Analysis:

“Wait Stat Analysis” is an alternate way to identify the symptoms that causes impact on the Server performance. SQL Server constantly keeps track of the reasons for which execution tasks wait or gets delayed; so to detect the reason, one can refer to the Server logs.

TempDB Space Review:

Another way for optimizing Server performance tuning is through proper analysis over the usage as well as empty and occupied space statistics of TempDB database.

Fragment\ Defragment Operation:

This approach can better be implemented through analyzing the indexes to detect the extent of fragmentation and to identify which indexes and databases needs to be defragmented for ensuring the smooth performance of these components.

Application\ Program Logs:

By referring to the “Windows Event Log” or “SQL Server Error Log”, the actual cause for inappropriate functionality of either database or SQL Server can be detected. This could help in identifying and rectifying the existing errors that leads to files inaccessibility.

Backup & Recovery Parameters:

For better performance tuning, analyze the backup and recovery settings to ensure if they are implemented appropriately. So that the backup files can be restored successfully in case of any unexpected circumstances.

Review Database Files:

Review entire database files including primary, secondary as well as log files (MDF, NDF and LDF respectively) to analyze and detect the actual cause that is responsible for the inappropriate functionality of database.

Deadlock Detection:

Detecting Deadlocks is not a major task but often requires proper understanding and hands-on experience on the concept to implement it in an accurate manner. To implement the task, it is important to understand the locking mechanism along with its resolution.

Hardware Components:

Regular examination test over the various components of the SQL Server machine is required to ensure smooth functionality of all the elements as well as to prevent the adverse circumstances that can take place due to major hardware breakdown.

DBCC Implementation:

It is very important to understand the nature of Database Console Commands as some of them are very critical and sometimes requires additional attention while execution. Some of these commands include DBCC SRHINKDATABASE, DBCC FREEPROCCACHE, DBCC SHRINKFILE, DBCC REINDEX and DBCC DROPCLEANBUFFER along with some stored procedures such as SP_UPDATESTATS.


So, these are some of the major mechanisms of SQL Server Performance Tuning concept and when implemented with proper consideration and attention, help in optimizing the performance of the Server. By executing these actions on regular instance of time; the performance issues with the Server and the incorporated databases can be resolved.
