Hi all, We have a four processor Sun box (each processor scores about 2400 pystones, whereas a 500 MHz P3 gets about 5400 pystones).
I have three zope installations running, one of which is hosting three subsites. If I create four *binary* installations of Zope (complete with the thread-safe MySQL adaptor and all the other python libraries necessary to run a Zope site), will I run into the global interpreter lock?
What I'm saying is if I *don't* use /usr/local/bin/python for my Zope installations, but instead rely on ZOPE_HOME/bin/python, will I be able to spread my Zope sites out over the four processors, or is there a nasty sting in the tail in doing this?
The interpreter lock is per-process, so if you are using separate Zope instances they won't bother each other. You don't even have to use different binaries -- /usr/local/bin/python will work fine *if* you spawn different Zopes. -Petru
