My Ubuntu 12.04 server comes with this cron job, which must be for cleaning up PHP session files
find /var/lib/php5/ -depth -mindepth 1 -maxdepth 1 -type f -cmin +24 ! -execdir fuser -s {} ; -delete
In my folder there are currently ca 1110000 such files and the server performance deteriorates because the clean up process never finishes. The server is virtual on a Xen platform.
Is there a more performant method available?
