I have a possible workaround for this problem. I still experienced the problem with the latest Ubuntu kernel (as of 20060724). In looking around I found this solution: http://www.vmware.com/community/thread.jspa?messageID=321981񎦽
Basically, the performance problems stem from ACPI bugs that set the kernel into the wrong "cstate". So, I did this: echo 1 > /sys/module/processor/parameters/max_cstate My performance problems were then solved (at least until a reboot). Hope this helps until a official fix comes out. -- kernel can't scale cpu frequency https://launchpad.net/bugs/36014 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
