I don't really know what is it you do, but I can give you a few indicators:
- Duron 1GHz, 256M, plain Zope + DirectoryStorage achieves an easy 30 reqs/sec
on relatively static storage (DTML).
- Same for heavier load (complex pages + images) does comfortably 20 reqs/sec
Both are straight to Zope, no caches!
- 2xAMD 2200+, 512M, ZEO + 1 client + Pound achieves sustained 120 reqs/sec on
normal pages (ZPT).
- 4 machines (each AMD 2000+, 256M), ZEO, 4 clients, Pound: sustained 280
reqs/sec, peaks over 400.
All of the above are long-term statistics from our clients.
I strongly suggest you have a look at your network topology, logging setup,
profiling, etc. In most cases the kind of problems you describe have little
to do with Zope - most often it's some name resolution problem or a badly
