Re: ULE/sched issues on stable/9 - why isn't preemption occuring?

Hi, Here's a trace with powerd/sleep states disabled, but I haven't set machdep.idle=spin. I'll try it with that in a sec. http://people.freebsd.org/~adrian/ath/ktr-notaskq-1.out.gz The entries are still out of whack in places, but it doesn't look like it's necessarily due to out of sync TSCs..

Concerning your hint installing the systen on the second SSD of around 16 GByte (marketing GBytes :-)), the BIOS by itself is unable to boot right. 16 billion bytes. A simple marketing trick to cheat you for 7.6% I think, it's only 7.3% $ bc (16*1024*1024*1024-160)/160*100 7.3

Hi, I've re-run the test with powerd and sleep state stuff disabled - lo and behold, UDP tests are now up around 240-250MBit, what I'd expect for this 2 stream 11n device. So why is it that I lose roughly 80MBit of throughput with powerd and C2/C3 enabled, when there's plenty of CPU going around?

usertime stale at about 371k seconds

2012-05-30 Thread Andrey Zonov
Hi, I have long running process for which `ps -o usertime -p $pid' shows always the same time - 6190:07.65, `ps -o cputime -p $pid' for the same process continue to grow and now it's 21538:53.61. It looks like overflow in resource usage code or something. Any ideas? -- Andrey Zonov ___
