Hi all,

We are in the process of migrating from Moses 1 to Moses 3. We have noticed
a significant slowdown when sending many requests at once to Moses Server.
The first request will actually finish about 25% faster that a single
request using Moses 1, but as more requests accumulate there is a marked
slowdown, until requests take 5 times longer or more.

Is this a known issue? Is it specific to Moses Server? What can we do about
it?

Thanks!

Oren.

Hi Oren

The threading model is different. In v1, the server created a new thread
for every request, v3 uses a thread pool. Try increasing the number of
threads.

Also, make sure you use the compact phrase table and KenLM as they are
normally faster, and pre-pruning your phrase table can help,

cheers - Barry
