We are seeking information on running Zope under an extreme load. Here are the metrics of the system that we would like to migrate:
# of users with an account: 40,000 # of R/O concurrent users at peak time: 5,000 # of R/W concurrent users at peak time: 5,000 # of (static) documents: 800,000
Your opinion on this topic will be very much appreciated.
I think that the weak spot could be the 5000 R/W users. That should certainly be tested. It also depends on what the 5000 users are writing simultaniously. Perhaps that cen be moved to a rdbms if nessecary. Other than that, your tactics look sound. Caching being the key here. Anything that can possibly be cached/ stored statically should be. Perhaps you could even have that in mind when designing the pages. Ie. by not putting something like "A clever quote" on the fronpage so it willl ned to be generated every time. regards Max M
