How can I speed up the load time of carrierwave / fog gems

Question

I can see that carrierwave is one of the slowest loading* gems (c.2.5 seconds) which is annoying when running tests in particular. Fog is also slow loading and seems to be included in the carrierwave gem anyway. Is there a way to optimize either the fog or carrierwave installations to speed up loading?

*when I say 'loading' I mean when running rails/rake/rspec

fog 1.31.0 carrierwave 0.10.0 ruby 1.9.3 rails 3.2

Answer 1

There is currently an effort to split fog into separate provider gems but unfortunately it will take some time.

Answer 2

I might suggest giving carrierwave-aws a try. They claim significant load time improvements over Carrierwave, along with "Significantly smaller footprint"
