DB Caching

[eluser]TheFuzzy0ne[/eluser]
Please can you a) confirm that the cache files are actually being written, and b) give us a genuine example of the code you're using?

I trust you realise that you can only cache read queries (such as select queries), and not write queries (such as delete, insert and update)?

One final question, how can you be sure it's the database that's slow, and not your server, or something in the script?
