I will try any reasonable test you guys have for me. Right now I am switching off HTT to see if that is the issue. This is a dual Xeon system.


The SCHED_4BSD doesnt do anything with HTT and in fact might hurt performance. If you are using ULE, there are several known bugs and its not recommended that you use it. So in short, turn off HTT in your BIOS on RELENG_5.


I am using the 4BSD scheduler, but I am really seeing some advantage with it. When it is switched off, multiply running programs really do seem to run a little slower.

But I'll switch off HTT for now.

Thanks, Stephen
