Enabling the high-resolution timer can increase processor usage on Windows agent computers. Typically, processor usage increases by 10% to 25%, but the increase can vary based on workload. Enable the high-resolution timer on Windows agent computers if you are measuring response times less than 15 milliseconds. Enable the high-resolution timer if you are measuring response times of less than 150 milliseconds and need 1 millisecond precision instead of 15 millisecond precision. If you enable the high-resolution timer on Windows agent computers, monitor the processor usage to determine whether the trade-off of higher processor usage is acceptable.
To enable the high-resolution timer on an agent computer:
