Measuring System Capacity
Measure how much excess capacity the system can handle without performance
degradation. To check capacity, you can compare performance versus load on the
existing system, and determine where significant response-time degradation
begins to occur. This is often called the "knee" of the response time curve.
Once you determine the current capacity, you can decide if resources need to be
increased to support additional users.
