Re: S3 docker registry performance

In general, S3 should be as efficient for the registry than EBS, and far more operationally easy (it also scales out horizontally).  

I don't know whether the encrypt option is done on the registry side - have you compared running with or without?

It's currently fairly difficult to move between backends - it's possible, but there's a lot of manual work you'd have to do.  I'm sure someone in the ecosystem has written a tool, but it's probably not efficient.

Does anyone have any comparisons of s3 registry performance? We've found it to be quite slow, at least 2-3 times longer then using something like an EBS volume. Here's the config being used:

      encrypt: true
      secure: true
      v4auth: true
      chunksize: 26214400

I stumbled across BZ 1314381 (https://bugzilla.redhat.com/show_bug.cgi?id=1314381) perhaps that could be one reason for slow performance.

Is it possible to migrate between different storage backends or is it something that needs to be decided initially?
