Hi Hugo, I've got a similar setup, Compaq DL580 on a Quad Xeon with 3gb of ram on Debian. To overcome the GIL and avoid dealing with CPU affiinity and to optimize server utilization, I started using Xen virtualization to create multiple virtual servers. It's open source and works great.
Check out http://www.cl.cam.ac.uk/Research/SRG/netos/xen/ or http://www.xensource.com. For performance see http://www.cl.cam.ac.uk/Research/SRG/netos/xen/performance.html This tutorial worked for me: http://www.debian-administration.org/articles/320 I also recommend installing xen-tools http://www.steve.org.uk/Software/xen-tools/ It's very easy to create new virtual servers: xen-create-image --host=apache xen-create-image --host=zclient1 xen-create-image --host=zclient2 xen-create-image --host=zeo To create and attach to a virtual server, just do "xm create zclient2.cfg -c" log in and install python, Zope and whatever else you need. So instead of running 1 plone instance at 22pps, you can have serveral plone instances running at 22pps each and no GIL problem.
