Microsoft SQL Server Performance Issues And Solutions

Anuraag Singh | January 8th, 2020 | sql server

When we talk about SQL Server, it is considered to be one of the best and widely used Relational database management system. This application is used by small and large scale organizations to store and manage tons of data. Microsoft SQL Server is capable to handle multiple operations. Also, the user can execute multiple Queries.

At some point, the user is going to experience MS SQL server performance issues, like memory or CPU related issues, poor queries or slow processing of queries, database indexes with reads and writes. So in the upcoming article, I am going to discuss MS SQL Server performance issues and methods to troubleshoot the problems. In case if you are facing SQL Server MDF file corruption issues then you can take the help of SQL MDF file Recovery Software to resolve those issues.

This informational post is helpful when the SQL database user is trying to pinpoint the root cause of the SQL Server of Microsoft SQL Server performance issues. But to interpret or fixing the issues is a Herculean task.

Issue1: SQL Database Queries Take longer Time than Usual in Processing

Sometimes the Queries takes a longer time than usual, this problem arises when the load or the processes to your system gets an increase. Also due to resource contention issues such as conflict due to shared resource or random access memory, disk memory, etc.

The user can try to solve these issues by using the Query analyzer and also with the system Stored procedure SP_WHO2 command. After this, the user will get the Blkby field. If SPIDS is being blocked then in the Output this will show the offending SPID Number. The user has to follow the large chain of blocks to find the head.

Issue2: If you are Facing Deadlock State Issue

A deadlock is a situation that occurs when the two processes are competing for multiple resources. And each process trying to acquire the lock on the object that the other process has already locked. When this situation arises SQL Server resolves this issue by automatically aborting the one process and by allowing the process to continue. But these deadlocks issues cause strain on the resources like on CPU. The user can try to avoid the deadlock situation by following this: 

1. Make sure the database design is properly normalized.

2. By keeping your transactions as short as possible.

3. By not allowing user inputs in transactions.

4. Avoid cursors.

Issue3: When You SQL Database Faces Out of Space Errors

While working on the SQL Server database the users have to face the database is Out of Space Issue. There are two reasons for this problem, the first one is related to the physical drive which stores the SQL Server database or its transactional log runs out of space issues. Second is that if the Transaction log file has set maximum file size. To resolve the problem the user has to increase the limit to allow database operation.

Issue4: Permission Denied Issue after providing then rights to Stored procedure

When the SQL user assigns rights to execute the stored procedure then the user has to allow the permissions on the object referenced by the stored procedure. To understand this let us take an example if you have stored procedure that performs the select operation from the customer table. Then you have to allow the user to select rights on the customer table.

Here Are Some tips to Handle SQL Server Performance Problems

1. Implement Those Indexes that give benefit to your Queries.

2. Make sure your Tempdb database is configured properly.

3. By checking the most time-consuming queries and stored procedure. And see if there is any room for improvement.

In this article, we have discussed MS SQL Server Performance Issues, and also share some tips to resolve these performance-related problems. In case if you are facing a problem related to the corruption of MDF / NDF file then the user can refer to the use of SQL Database Recovery Software. This will helps the user to resolve the corruption issues. Also, the user can preview and recover deleted SQL table records in red color.
