Re: [Xen-users] Xen vs VMWare comparison paper

[John Sherwood <jrs@xxxxxx>]

Hadn't seen it, but the fact that they used 32 bit Windows Server 2003 means that I think it would be - to say the least - disingenuous to extrapolate those findings to Xen in general.  Running windows means that it was running HVM and that's a killer for IO based testing.

In other words, if you - like the vast majority of Xen users - are running PV guests, this is 100% irrelevant.

One of my customers handed me a copy of this paper and asked why are we using xen if it is so slow...

http://morse.colorado.edu/~tlen5710/12s/VMware.pdf

which is a fairly damning report of performance under Xen in comparison to VMWare, citing worse than 50% overhead of Xen in comparison to physical.

Has anyone seen this paper before?
