No. It does seem like if I stop and start very quickly on my Mac, the  
startup is pretty quick, just a few seconds. But if I wait 30-60s  
after shutting down before starting up again, it's slow again. But  
it's not always quicker on the quick restart.

Otherwise, the only other thing I've noticed is that it's never slow  
with static mod_perl1.

Where do I find something to tell me how to use strace with Apache on  
Mac OS X? Pointers appreciated.
