Fast 404

module installed and configured. not tested yet.

Since we expect a bunch of 404s due to the mcmlter re-routing, we may need a bit of extra handling for a while. Here is the scoop on fast 404

"Drupal has expensive 404 errors. On an 'average' site with an 'average' module load, you can be looking at 60-100MB of memory being consumed on your server to deliver a 404. Consider a page with a bad .gif link and a missing .css file. That page will generate 2 404s along with the actual load of the page. You are most likely looking at 180MB of memory to server that page rather than the 60MB it should take."
