predict() takes a very long time #22

Hi. I trained an FM_FTRL model for 5 iterations which took 5 hours on 120 million records data.
But when I try to output predictions on this trained model, it takes a very long time (I end up killing it after it runs for 1 hour).
Is this normal ? Is prediction supposed to take this long ?
I use the latest github version of wordbatch: 1.3.5.

By the way, pickle_model() does not seem to work, it uses get_params which is not implemented.
I ended up using regular pickle.dump()

Thanks,

Not normal, the testing should take less time than training, since training is prediction+update per row.
