[Balint Pfliegel]

1) Always listen to Sven
2) Never allocate, just reuse objects - gain is around 3x, if you have a lot of allocations currently.
3) Make sure you have at least an ok eval (if Shannon is the original Shannon formula, maybe you could at least add a piece square table to it).
4) If you want to cut, you must focus on move ordering first (MVV/LVA, killers, TT, etc). If you don't have a good move ordering, you won't be able to cut efficiently without doubt.

Good luck, Balint
