Now I have installed the firebird 3.0 rc2, the performance is great, superservers takes all cpu-cores and the problems now banned. I have not changed anything, is this a result of the superserver or the version 3 of firebird? Both. Firebird V3 introduces parallel execution of queries in SuperServer. SuperServer was always multi-threaded but only one thread could run at any one time even on a multi-processor server. The benefit of threading in earlier versions was that queries could be interleaved, so a long report didn't block all other requests. With V3, thread do run in parallel taking advantage of all the processing power of a multi-core machine. Glad things are working better for you! Good luck, Ann
