As a long time Perl mailing list subscriber, I'd say the "pace" of Perl Monks is definitely quicker than most mailing lists. That is, threads get responded to quicker, and they also seem to die quicker. It's rare when I respond on a mailing list to find someone has beaten me to the punch by a few minutes, yet that seems to happen all the time here. ;-) And it's not only me who's noticed this; I remember once kwilliams being so surprised about how quickly thread Module::Build and the PPM seemed to die (compared to a typical M::B mailing list thread) that he asked the M::B list what was going on here.

Of course, there are many exceptions to this and the other side of the coin is that long "hibernating" Perl monks nodes spring back to life far more frequently than do mailing list threads. I've often seen feedback on Perl Monks nodes that are several years old yet I can't recall ever seeing that happen to a mailing list thread.
