Subject [jira] Commented: (GERONIMO-4947) Geronimo performance
Date Tue, 10 Nov 2009 17:57:27 GMT


Donald Woods commented on GERONIMO-4947:

Well, Win2000 Server came out before the virtualization wave, so you're reliant on VMWare
providing you with decent virtualized drivers, which will always be slower than the para-virtualized
drivers now available in Win2008 Server w/ HyperV support and most newer Linux distros (like
SLES 10/11 or RHEL5).  I remember trying to run Win2000 and Win2003 on VMWare Server (free
edition) and there was a very noticable performance impact, especially with disk IO.

I've been using Win2008 w/ HyperV to run 3 guests Win2008 VMs on a 8 core server and am seeing
only 5-10% performance impact for a guest OS vs. the host OS.  For SLES10 SP2, I'm running
2 guests on a 4 core server and seeing 5% or less performance impact..... (both are my casual
observations while timing builds and testsuites using the system clock.)

Only thing I can suggest, is downloading a Win2008 trial copy and trying it on VMWare (latest
Server or ESX)...  You could just be running into limitations of 10+ year old Windows software
or in a back-level version of VMWare...
