Hi Marcin Is this single-threaded or multi-threaded Moses? One possible issue is that threads are now compiled in by default, so even if you run with a single thread then you still pay some locking penalties. I'm not sure that this should make the large difference that you observe though. You can compile without threads to avoid the locking.
I haven't noticed any significant slow-down, but we don't monitor performance too carefully here (although we probably should). I'd be interested to see a profile of the two versions that you tested, cheers - Barry On 05/08/12 11:27, Marcin Junczys-Dowmunt wrote: > Hi, > has anyone noticed that Moses seems to be about 20-30% slower than about > a year ago?
