So... I look into the problem. Yes, the page either loads up fast, or times out. So, into the logs I go. Webserver is fine (except the timeout), PHP though... Error log is fine (just notices), but slow log shows the issue is the database (of course... its always the database... ugh)

So, checking the database, there is one ugly query that seems to be an issue. 5 joins and a huge where condition.

So I run EXPLAIN on the query and... Proceed to bang my head against the wall.

OF COURSE ITS SLOW YOU FU******, NONE OF YOUR TABLES HAVE ANY INDEXES.

What do they expect when the database has to always go down the whole table and do everything in memory, until it runs out and has to dump it all on disk and work with it there.

Ugh... Some clients...
