Woha, that's news to me ! Thanks !

Seems to be the most straight forward way to work arond this is to use -i
option ... Though I suspect the 2.4 kernel, and maybe 2.6, might have ways
to bind to specific CPU's ... Something to keep in mind anyways.

I'm curious, why pystones / 50 ? My machine is a 4 CPU, do I still use 50 ?

Also, my pystones/50 is 156, which, from reading what i could find on the
topic, is low (Default Zope is 500, Plone talks about 750).
Mind you the server as a whole isn't very busy (Linux's procinfo says 85%
idle!)

Is this right ? Also, should pystones be run on an idle system ? Does it
matter ?

Thanks to this, I've now discovered the -O option, which I've already put
into use, we'll see if that improves things.

Thanks again for the eye opener ...

J.F.

That is correct. Read this:
