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).

  Are you running the list with personalization on?  That would mean 

40k individual e-mails. Even then 90% CPU seems high - when I do my 4k list it take a while, but does not run that high. Unless I virus scan the lot, then the virus scanner eats the CPU alive.
