Could you offer some your system information like cpu, mem, disk?

The Problem is that CRF++ needs lots of memory while training. If your box's 
starting
to use swap, it'll be very slow to finish the training. So, to build a crf 
model fast
it needs at least 1GB physical memory. That sounds horrible, but training is 
indeed a
memory bound process.

with my 1GB Thinkpad X60, it took about 12hour to finish the training.
