Initial basic checks before proceeding to DB tunings in MSSQL:
Check your SQL Server environment before tuning for performance
Sometimes when we have issues with slow response for our DB queries, we think of tuning the query assuming the SQL Server is tuned and it may be problem with queries. But it is observed that it is better to make a common practice to check the basic configuration settings of the SQL server before we start to analyze the queries deeper.

Placing the files on separate drives allows the I/O activity to occur at the same time for both th…
