CPU speed has relatively little to do with performance issues on
things related to Internet mail and mailing lists. If you're short
of RAM, that can be a real problem, but 1.5GB is probably enough to
avoid the worst of the sorts of problems typically caused by memory

I recommend going to the Mailman FAQ Wizard at
<http://www.python.org/cgi-bin/faqw-mm.py>, search for "performance",
and read the various entries which are returned. You may want to pay
special attention to the entries at
and consider the performance advantages of upgrading to version 2.1.5.

It loads the Python pickles, yes.

It's hard to say. There's a wide variety of reasons why this
could be happening, but most of the known issues are detailed in the
FAQ and can be found by searching for the word "performance".
