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).
