[Mailman-Users] High CPU Load

[Jason Shouler]

Can anyone offer any suggestions on resolving a high cpu load with Python.

We're using Mailman 2.1.4, Python 2.3.3, Sendmail & Amavis to support an 
announcement only list of about 40k members on an IBM Netfinity server 
(1 Gb RAM).

During list activity CPU load will often exceed 90% with the load being 
spread fairly evenly between active qrunners (e.g. command, outgoing & 
virgin runners).

This I can live with but what I can't live with is the 98% load 
generated from the web admin interface (driver admin script) which 
effectively makes the interface unusable.   In fact mailmanctl must be 
shut down in order to do any remote administration at all!

I've scoured the archives and also tried most options within 'mm_cfg.py' 
all without success.

It's probably worth pointing out that the same issues existed with 
previous versions of Python and Mailman.

Suggestions anyone?
