no, the unreasonable cpu ticks are still there in 2_0_28, so we can't use them to help debug the load spikes. Brian P suggested the former might be due to spin locks. > Eyeballing a "tail -f weblog" I just see ticks in the 0-3 range, with > almost no 3's and lots of 0's. yeah, something like 98% of requests have less than 3 cpu ticks. > (But I didn't whip out /usr/bin/perl to do a real check.) well, I did and I saw a few negative numbers...wtf?!? It doesn't matter, this patch isn't helping us now anyway. Greg
