Fixed Time Quanta (FTQ)
The FTQ benchmark takes a time based approach, rather than a workload based, approach to analyzing deterministic processing behavior of operating systems. The time based approach allows for more advanced analysis of the results than workload based benchmarks. For example, with results in the format of "units of work per fixed time period" rather than "amount of time per fixed workload", the analysis can examine the frequency domain and point to periodic problems.

Who's using FTQ and for what?
FTQ Visualization Tools
The output if FTQ is raw data in two files, containing time in one and corresponding units of work in the other. Any number of scientific analysis packages can be used to visualize and interpret these results. I have put together a frequency domain visualization tool which plots the time plot and the fast fourier transform of a pair of output files. It uses python, numpy, pylab, and scipy, to present interactive plots.
