This is a very possible explanation! You are right about your assuption that the second query is fast. First one is really slow, next ones fast. But if I change the queryterm it is slow again. Next query with the second term is fast again.

So it looks like a caching problem? Or is it a I/O problem?

Is there anything I could do to avoid it?

'schul' is no whole word, it could be part of a name e.g. Schulz. This is why I could not use FULLTEXT. The query is used to find users whith a username that contains the querystring.
