I really think the fact remains that the guest dom he's running is a bit overloaded; and running non-optimized settings.
Namely the I/O is probably killing you (with whatever writes it may be achieving); Either run critical write portions in a RAM disk, optimize your guest, or run in full hardware. You have other options, but ultimately you're doing too much with one guest dom given the load you've displayed. ~B On Fri, Sep 9, 2011 at 12:19, John <[email protected]> wrote: > We actually see very good performance here with optimized (using PV or HVM > w/stubdoms and GPLPV, with various kernel and configuration tweaks) Xen > setups, to within a small percentage of bare-metal.
