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

Thanks Kevin, It's a very good architecture option. I'm afraid a bit too late to test.. I'm already in production with the new architecture and CPU affinity. It's running smoothly though.. :-) Regards Hugo On 3/22/06, ksmith99 [EMAIL PROTECTED] wrote: Hi Hugo, I've got a similar setup,

Why do you want to do this? Do you believe that this is more effective or efficient than the scheduling algorithm that Linux uses? Binding an application to a single processor makes very little sense at all. If Zope really is your limiting factor, then you need to spread that load over as many

a) Your system may be I/O bound - not CPU bound - so you will never see the CPU max out because the limiting factors are memory and disk/ network access. b) Make sure to tune Python's checkinterval. While you should *always* do that, it is especially important on multi-processor/multi-

Thank you all !! (very insane multiple exclamation marks) I've been trying different scenarios and Zope performance increased 10 to 11 times faster... Cheers Hugo On 3/16/06, Stefan H. Holek [EMAIL PROTECTED] wrote: a) Your system may be I/O bound - not CPU bound - so you will
