Hi Hugo,

I've got a similar setup, Compaq DL580 on a Quad Xeon with 3gb of ram on
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

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.
