How to check the performance of SQL Server?
You can get the most out of this behavior, and check that SQL Server is handling queries as expected, by monitoring these metrics. To get a high-level view of the overall usage of your database over time, you can measure the number of batch requests the database engine receives per second.

Why is SQL Server a slow I / O driver?
If SQL Server is the main I/O driver and I/O volume is beyond what the system can handle, then you need to work with the Application Development teams (or application vendor) to tune queries – better indexes, update statistics, re-write queries, re-design the database, etc.
