...biz list I think I will find my target audience here. We are looking to hire a consultant to help us figure out an issue. We are having what seems are "random load" issues with bare metal boxes that are dedicated to Asterisk and a few Perl AGI's. We went after all the usual suspects (CPU IDLE, memory usage etc.). I wrote the simple bash script below to show me total calls and CPU usage of Asterisk #! /bin/bash for i in {1..50} do CALLS=$(asterisk -rx'core show calls' | head -n 1 | awk '{print $1}') CPU=$(top -b -n 1 | grep $(pidof asterisk) | awk ...

Hello, I searched the mail list, but can''t find a solution. I have a machine with 8 cores. I want to set the CPU affinity for dom0. For example, let Dom0 use processor 0-3, let guests use 4-7 For guest domains, I can do this by setting the "cpus" For dom0. there''s no such option. The only one I know is in /etc/xen- config.sxp, which has "dom0-cpus" setting. Someone suggests that...

Hi This patch fixes code generation bug - 586-class CPUs don't support the nopl instruction and some 686-class CPUs don't support it too. I created bug 17792 for that. BTW. I think you should also optimize padding on these CPUs - instead of a stream of 0x90 nops, you should generate variants of "lea (%esi), %esi" instruction like...
