What is "warmup time"?

Dec 26, 2008 at 9:06 PM
Lab 4 .7 says to "Select a suitable warmup time and duration." However, it does not explain what a "warmup time" is used for. What is the purpose of a warmup?

Often when you do a load test of some sort you want the test to represent normal operating conditions, when caches are populated, code has been jitted etc. The warmup time is therefore the period of time you run the test before you start recording the performance, to allow theses things to happen.
