Has anyone had experience running SuSE on a Dell PowerEdge 1750. Or a
dual Xeon with hyperthreading. We
have installed Suse SLE 9.0 with no problem but are seeing poor
performance. I/O operations are much faster
than our legacy hardware (PowerEdge 500) but processor intensive
operations (ie garbage collection and searching documents) perform
much worse.

I know that these are vague criteria, but I'm just trying to get a
handle on general configuration issues with dual processor /
hyperthreaded machines
and the latest Suse distros with kernel 2.6.

For example: the install set my grub arguments to have acpi=off. Some
of my reading suggests that I may want to change this to: acpi=ht

What are the ramifications of doing this? It turns on hyperthreading,
but do I need to do anything to my kernel before doing so?

The application in question is a Java web application running on Tomcat.

Any insight would be much appreciated.

Thank you,
