Roger Pau talking about Performance tuning Xen at the CentOS Dojo

The first edition of the CentOS Dojo takes place on Monday  8th April at the Don Bosco School, Antwerp and Roger Pau Monné is running a Xen specific session there. Synopsis of his talk, titled ‘Perfomance tuning Xen’ :

How to tune your Xen deployment for performance: Xen has several options and different kinds of guests, knowing when to use each kind of guest, and how to tune its parameters for optimal performance can make a big difference.
