about detect speed

[chengjunjiecn]

data/demo/009.jpg Detection took 8.986s for 5 object proposals

detection spend about 9s, is it ok?

@chengjunjiecn I did not test on cpu. with gpu, the speed can be reduce to 0.4s per image

I have the same problems. With default demo.py, it costs about 2 secs per pic, while I set the tf.app.flags.DEFINE_string('gpu', '0', '') to tf.app.flags.DEFINE_string('gpu', '1', '')

it costs about 1 secs per pic. How to speed it up to 0.2s per pic?
