Windows 2008 on VMWare ESX 3.5

Xinn · 19 Mar 2009 at 14:42

Is anyone running Server 2008 and ESX 3.5 and getting terrible performance?

There are a few similar cases on the VMWare forums but nobody seems to have a reason why?

Formatting disks is taking hours. 10+ mins for 18Gb disk, I daren't even start the 330Gb one going.

Host spec is: 2x 2.7 Dual Core Xeons, 48Gb memory

Ofcourse running several other VM's.

Guest is set to 1vCPU and 4Gb memory, it is running VMware tools.

3.5 u3 solved our performance issues with 2008

I'll vmotion it onto another host, we updated one host to u3 last week, will see if that helps.

It would seem I can't migrate it to the box with U3 on because some clever person decided to turn off x64 on that host *claps*

The other hosts are all on u2.

Damn this Exchange Pilot!

No problems here. Running 8 x 2008 (4 x 32bit DC's, 4 x 64bit Exchange instances) VM's.

ESX 3.5 U2 (rel 110181) on Dell R900's. 4 x Quad, 128GB RAM.

We have a couple of brand new R900 due sometime next week same spec as that which these 4x 2008 VM's will likely end up on so hopefully we won't have any problems once we stick them on there.
