PHP Cache

Please forgive the terrible loading times. I was dugg a while back ago and the server seemed to hold well but after being Boinged, the server is taking a strain - the culprit being MYSQL. I threw together some makeshift caching for parts of the site which is why it now loads in blocks - but will be spending the rest of this week working on some caching algos so that the DB is not accessed unnecessarily - please bear with me for a bit longer :-(
If you are looking for some caching solutions, I suggest Cache_Lite which pretty much works out of the box.
