It's pretty hard to say, even with the data you've provided. But, try adding &debugQuery=on and look particularly down near the bottom there'll be a "<lst name="timing">" section. That section lists the time taken by all the components of a search, not just the QTime. Things like highlighting etc. that can often give a clue where the time's spent.
What sort of wildcards are you using? Did you have to bump the maxBooleanClauses? This is a bit puzzling though....
