Result looks OK with a SuSE kernel (I think they have lowlatency patch applied), worst was ext2 - it was diskread that had most problems... ext3 - diskread (!?) diskrm included for reference http://w1.910.telia.com/~u91005836/index.html [I have to recheck the results when I am awake :-] Patches are attached - with extras (see below). Hmm... the output should really add kernel version: uname -r "2.4.21-215-athlon" Close, but does not tell that it is precompiled by SuSE X11 server and filesystem type: how to find that automatically? I use, XFree86 nv Extras: * some filehandling (non local root of testing) and * run with min(SCHED_FIFO)+1 not max - it is a CPU hog (80%) [the more CPU usage the less prio] - show that it works to avoid creating a trend... /RogerL -- Roger Larsson Skellefteå Sweden
