[LAU] benchmarking your audio system

I had the idea in mind to test my machine (and trying to benchmark the tests), loading the session with a chain of JACK clients, in order to know the limits of my system and in what conditions the system is stressed, and when I would have more chances of XRUNS. The chain would be something like this. *playing a midi file with Rosegarden (a midifile full of tracks) *fluidsynth as a soft synth, loading a heavy soundfont. *JACK RACK for LADSPA effects (load several processor consuming effects) *recording the session into Ardour, at the same time that monitoring the output to the speakers Meanwhile I will monitor the system performance (processor & RAM). (I thing that Conky System Monitor would do the task of saving a log file for later parsing). I don't know if it is possible to fetch the number of XRuns from a file or log. Questions: -how can I stress even more this test? -is it possible to make this process standard, searching for a general method trying to say if this machine, this configuration or this OS is better than other? -is there something left that I need to take into account? -is all that a good idea? thanks (this is just an idea, I won't have time in two weeks to implement something similar).
