I'm measuring the performance of a certain lengthy set of calculations on a dedicated computer. I can control the length of the set and need to measure calculation times.

There are standard tests that do this, programs you can download. You may be able to learn more on hardware test sites like http://www.tomshardware.com/
If the calcs are long enough, you could time each and track the mean time per calc. Otherwise only taking time estimates every N calcs, and dividing by N. The average over N could be used to help calculate the overall average. When you notice the calc time has dramatically increased over the overall average time, you could guess the system is paging.
