Virtual Server CPU performance

[xgene_2]

We have a proliant dl360 g5 with 2 dual core intel Xeon 5150's. This server is running windows 2003 Server sp1 and Virtual Server 2005 R2.

We are hosting 2 virtual server guest instances (each windows 2003 sp1). Each instance has ~ 2GB of RAM allocated. Is there a better type of CPU we could use in this hardware for this setup? We have had a few performance problems CPU-wise already and are wondering how we can better this performance. These are only Web servers.

any ideas?

(We've tweaked several ressource allocation settings within virtual server without much improvement.)

How many CPUs have you assigned to the guest instances?

I have not played with Virtual Server yet but from a VMWare perspective there are issues with assigning the same number of CPUs to the guest server as the physical host due to the way CPU is scheduled.

Well from my understanding virtual server 2005 R2 (no beta service pack) you can only assign one "logical" cpu. to a virtual server...

since we are using 2x dual core 2.6 Ghz Intel Xeon 5150's, We are apparently getting 1 core, and I'm pretty sure it's not getting all of the 2.6 Ghz of processing power...So I guess I want to know if I can improve this somehow... (Virtual server 2005 r2 SP1 is supposed to allow to add more than 1 logical cpu but I haven't tried or seen this...and virt serv 2005 r2 "sp1" is only in "release candidate" right now...
