Hi,
Did any of you perform researched into the decrease of performance
when running Geoserver in a virtual environment like Xen or VMWare?
Theoretically, there shouldn't be any noticable effect, but I'm
interested in numbers.
Kind regards,
Pieter

Paravirtualized systems on Xen suffer neglible performance loss. I've mainly tested CentOS 5.2 on CentOS 5.2 and it's 50/50 whether the virtualized or the native machine comes out on top (neglible differences). I used 4 CPUs and 8 Gb RAM while testing on Xen 3.3.0. I can give you my numbers from the phoronix benchmark suite, but they're really not interesting since they're identical. I have no reason to believe GeoServer would behave any different than the programs in this suite.
Note that Windows does not support proper paravirtualization, and I think you're limited to one CPU, at least in Xen.
I don't have any updated numbers for VMWare, a few years back they were trailing by about 20% compared to native, they obviously can't outdo Xen.
