Using SQL Server Monitoring Counters To Evaluate Performance
SQL server counters are special tools used within SQL server monitoring. They enable you to measure many aspects of SQL Server performance. Gathering this data over a period of time lets you view past trends to learn how to optimize your server for the future. You can utilize counters for your preferred metrics. Counters aid DBAs in identifying and solving SQL server performance issues.

Here are 5 common SQL server counters you could use while optimizing your SQL server.
1. Buffer Manager: Page Life Expectancy
A counter of page life expectancy will measure the amount of time a page stays in the buffer cache. Their unit of measure is in seconds. If a page remains in memory it does not require SQL server queries to read from a disk. The performance of the system will increase with increased page life expectancy.
2. Batch Requests/Second
Batch requests/second measure the number of batches SQL Server receives per second. This will indicate the amount of activity a SQL server is experiencing. Higher numbers mean a higher number of query executions. Optimization of a SQL server requires you to take these measurements often to discover the SQL server performance over a period of time.
3. SQL Compilations/Second
SQL compilations/second measures the number of times SQL Server compiles an execution plan per second. This procedure is very resource intensive and can hurt your SQL server performance. The comparison of SQL compilations/second and batch requests/second enables DBAs to determine if compilations are a cause for poor SQL performance.
4. Buffer Cache Hit Ratio
The buffer cache hit ratio measures how often SQL Server finds data pages in its buffer cache when a query requests one. Performance improves as the number reaches closer to 100. Essentially it means that a SQL server was able to grab necessary data from memory and not from a disk.
Learn about the benefits of SQL Server optimization.
5. Lock Waits/Second
Sometimes SQL servers must lock the system resources to be able to handle the increased numbers of users using the system simultaneously. The measurement of lock waits/second refers to how often a SQL server was not able to retain a lock. Being unable to retain a lock can hinder SQL server performance. In a perfect world this number would be 0. As numbers stretch further from 0 performance will decrease.
