Re: Weird context-switching performance [RESOLVED]

Situation resolved. Turns out there was one small line in a kernel config file that we overlooked. Seems the apm device was causing a massive performance penalty. We don't really need it so we removed it. All performance metrics are now exactly where they should be. -- Milo Hyson Chief "Mad" Scie

We don't have any other systems that are as similar as the two in the test, however we did plot context-switching performance against CPU and memory performance on several systems to see if anything jumped out. We found that beastie (the 2200+) is doing only about 26% of the task-switches/dhrystone

Weird context-switching performance

2004-01-31 Thread Milo Hyson
We've got these two very similar machines that are exhibiting drastically different context-switching performance. The slower of the two is actually task-switching at four times the rate of the other. We've gone through several benchmarks and are at a complete loss to explain it. We've set up a pag

Yeah, the problem with these is they're a single 48v input. I have an A/B redundant 48v DC battery backed generator backed plant on the telco side, and a fair amount of extra capacity... So I'd like to take advantage of it. But thanks for checking. On Fri, Jan 30, 2004 at 09:39:06AM -0800, Broo
