Fugliness

The db stuff is much less than that actually - I'll have to insert more profiling calls to figure out why loadcontent takes so long (I have an idea), but the actual db access is in Revision::loadText, which is only 0.088 seconds. The profiling info also contains all the database queries, but I didn't write them down - they were really quick, so it's definitely not the database. And even 0.3 seconds is relatively small compared to the total.

True, but I hope you're right that the DB stuff is less than 0.3s - it should be (essentially) zero for a system of this size.

I'm not trying to annoy here, but please just take a look at the indexing anyway? Yes, it's mainly down to the parser, but every little helps.
