I ran similar tests to what Torsten had, and definitely noticed a
difference in memory usage, but didn't see any leaks in memory. Memory
usage is about twice when using $r->print, but it does hit it's max fairly
quickly. Memory usage also maxes out fairly quickly using the bucket
brigade method. Maybe the leak has been fixed? I'm using apache 2.2.21
and mod_perl 2.05
Thanks,
Dimitri
