We noticed about a week ago that Docker image pushes to [Quay.io](http://Quay.io) have gotten a lot slower. Pushes to Quay are still quick from our own EC2 machines. Did something change on Circle’s side? ---

What kind of data transfer speed are you getting now? It would also be great to know what was the bandwidth you were seeing previously. ---

`docker push` doesn’t report bandwidth, so it’s hard to tell! We didn’t have any formal benchmarks setup before this issue, and haven’t made any since. From builds before and after the slowdown, I can see that `docker push` used to take ~1m and now takes ~5m. In both cases we’re only pushing ~15MB to Quay. ---

I am afraid this might be a question for [Quay.io](http://Quay.io) support. We haven’t observed any network issues recently, and so we don’t think this is directly related to any of our actions. Thank you for your understanding. ---

Late answer but I noticed in debugging CircleCI is using Docker v1.8. In Docker 1.9 there is a fix for the buffering to disk that greatly speeds up pushes. I filed a ticket pointing this out and hoping they default upgrade. In the mean time I’m trying to figure out how to script a forced upgrade to docker 1.9 ---
