I'm trying to move from the moses 1.x release to 2.x, but have encountered
large performance issues. On my workstation (Scientific Linux 6.5), using
the same spa-eng data to create two systems I get performance roughly 3x
slower on release 2.1.1.
I started by comparing moseserver between the 1.x and 2.x releases. After
discovering the "single phrase cache per thread" issue, I rewrote
mosesserver using a thread pool but only got a 10-20% improvement.
Thinking I might not really have fixed mosesserver, I tried comparing
unmodified moses-cmd speed between releases. The values are in words per
minute for a 2000 line, 48k word file.
1T 4T 8T
Rel 1: 4850 16492 19500
Rel 2: 1742 5324 6559
Any suggestions?
Regards,
mike.
