[Mailman-Users] Mailman performance

[Dan Mick]

Doesn't surprise me.  It's an interpreted language, so loading up the 
interpreter, then the code, then executing is going to take a 
certain fixed startup time.  It will be completely dwarfed by
mail connection time when you start running an actual list.
