[Zope3-Users] threads, pool size and cache recommendations (quad core)

[Roy Mathew]

Hope this helps make things a bit clearer:

Concurrent users: 100
Concurrent requests (worst case): 100
Concurrent writes: 1-2 per request
Application: online quiz
Data written: small updates (100 bytes, approximately)

Thanks... I am just looking for some rough guidelines.
