I run apache2, ssl, mod_perl and php. I have yet to hear complaints from my perl or php programmer. Without have another PHP vs. Perl "thing" lets all agree that they are both pretty nice :) > Run the Unix OS you're most comfortable with, knowing that PostgreSQL > gets lots of testing on the free unixes more so than on the commercial > ones.

I'm not sure I heard any mention of filesystems but I've been moving all my EXT3 filesystems to XFS. Some other journaling filesystem that you might want to look into are JFS and ReiserFS. -- Keith C. Perry, MS E.E.
