This server moved to apache 2.0 recently. Apache 2 has been out for so long, it’s a miracle I didn’t switch earlier. The machine here is a dual PPro/200 with 64 MB (as I have repeatedly whine about), and apache 2 is more resource-efficient and runs much better on SMP machines. The apache processes used to eat 12-15 MB, now they just use 6-8 MB, which is pretty decent.
Of course the whole thing wasn’t without problems. Migrating all my site-specific settings took me a couple of days — mod_python enabled directories, the php things, etc – and the SSIs still don’t work everywhere, I’m sure. But all in all, it’s much cleaner and I’m happy with the move.
