there was a discussion of the slowdown due to multi-threading. http://article.gmane.org/gmane.comp.nlp.moses.user/5193/match=multi+threading+boost+lib+compile+error+threaded+moses i found it to be about 10% slower for hierarchical model. It may be slower for phrase-based since that has more locking. I think it's an inevitable trade-off between speed and having threading.
i don't thinking anyone's mentioned it since then. On 05/08/2012 11:27, Marcin Junczys-Dowmunt wrote: > Hi, > has anyone noticed that Moses seems to be about 20-30% slower than about > a year ago?
