upload unchanged files to S3

[ming-kernel]

I am using asset_sync (0.5.4).
And it uploads lots of unchanged file to S3 (image, js); how to config asset_sync so that it only uploads those files changed?

I think the problem is not on asset_sync version rather on your sprockets version.
I suggest that you upgrade your sprockets/rails gem because the most recent version of sprockets already has this feature.

I have the same issue using sprockets 2.12.2 and sprockets-rails 2.1.4 (latest)
It takes forever everytime i push

have you tried using rake assets:clean to rebuild/delete your precompiled files.
That might solve your problem.

rake assets:clean doesn't do anything in my case.. I ran it locally and on heroku
