How does the Grinder calculate the mean time and TPS?
Each worker process records the time taken by each thread for each test and regularly reports the mean time for each test to the console. The console calculates the mean time for each test across all worker processes. This is the mean time. Tests per second (TPS) is calculated by the console. It is the sum of the number of tests performed by all worker processes within the sampling period, divided by the duration of the sampling period. Using longer sampling periods will give better averages, but the console display will be updated less frequently.
