This was not a synthetic benchmark, I would consider this a 'real-world' problem now. Repeating the test with ext3 would just tell you whether it has the same problem. If it is neccesary to get the reiserfs issue addressed, I will repeat the test with an ext3 system in the next few days, I would like to hear from reiser on this before doing much more. > Note that this info because available because someone set > /proc/asound/*/*/xrun_debug.
