Run as many Zope instances as CPUs you have if you wish to take advantage of this in Zope:  i.e. 2 CPUs == 2 Zope Instances.

You will basically double the performance of the server with ea. CPU/Instance.  At some point there might be a diminishing return, but I doubt any of us have that kind of hardware J

Subject: [Zope] 2 Zope instances on a 2 CPU linux server

Hi,

I would like to know what if using taskset (CPU affinity utility on linux) to bind each Zope instance to one single CPU can improve overall performance of both instances in any way ?

As far a I know, python can not fully take advantage of 2 CPU cause python threads are not OS threads.

Thanks.

Pascal
