Found it. The granularity on the stime and utime is basically __hz - so > on a kernel that uses CONFIG_HZ=100, we only have 1 or 2 digits of precision here. > Even with CONFIG_HZ=1000, we barely get 3 digits. > > Is there any way to get REAIM to loop around several hundred times, so the > times are into the 1-10 second range rather than hundredths of a second? If we > get the CPU time up to the 5-10 second range, we'll get 3 digits even at HZ=100.... Should be doable, and I can make that change in the local copy of the reaim sources, but I won't have a chance to look into it until next week at the earliest. > (What does "zcat /proc/config.gz | grep -i hz" give on the test boxes, anyhow?) Nothing... -serge
