How to speed up feature extraction?

[Chrisdy]

I have run the feature extraction example on ubuntu as follows:

./bin/linux_64/overfeat -f samples/pliers.jpg > pliers.txt

my sys info are as follows:

                           system         System Product Name (SKU)

it costs 2m27.607s，is there anything I can do to speed up it?
