Did you run hdparm /dev/sdb as a baseline before upgrading to Server2 Beta? After?
No, never occured to me as I didn't have the problem. I only noticed after the upgrade that copying takes forever and the guest kinda freezes until the copy is done. Only when I started looking into it I noticed I have a 85% drop in disk performance between Host & Guest. I can live with say 5%, but 85% ?!!
Probably part of the reason why Server 2 is still beta. From everything that I've read, and talked to others about, Server 2 is a dog. We're still running 1.0.4 on most of our hosts with no immediate need to upgrade.
Well, if this post fails to sort the problem, I'll see if I can post a Bug for Beta2.
I would however like to be sure that it's not just something I've missed or configured wrong before I make it an official bug
I find the performance in the newest VMWare Server 2 Beta is slightly better than previous versions of VMWare Server. Machines run smoother and seem more responsive (excluding the disk performance problem of course), well that’s my opinion in any case
Nobody else with any advice?
Read this thread:
"The big-picture answer is that the Linux virtual memory subsystem is simply not tuned for running VMs. No OS can be the best at everything. If you really want to be at the higher ends of transfer rates for your storage devices, ESX is a much better option"
so linux is not the best choice to run vmware server ...
I am on ubuntu - a small home server with only 4-5 vmachines - and my windows guest are pretty slow regarding disk performance.
