I've been using Apache::Session::MySQL for a while, but I've been trying to lower the amount of database I/O in some applications that experience spikes in server traffic. So I came up with the idea of using Apache::Session::File with the files on /dev/shm, with a cron job to clear up old or expired sessions. Preliminary benchmarks found this to be about 7-8 times faster than MySQL.
I'm curious if anyone else has tried this, and if they can think of any reasons why this would be a bad idea. Dan
