Please don&#x27;t use Quay for official open source images if you care about international users, or at least offer a Docker Hub option as well. Quay is super slow compared to Docker Hub. When I contacted support back in July, they were very polite and professional, but in the end &quot;everything is being served from AWS&#x27;s US East region&quot;. Peak time performance is intolerable. It was so bad that our systemd units were timing out even with a massive 5min TimeoutStartSec.<p>To worsen the issue, Quay still doesn&#x27;t seem to support parallel layer downloads, and Docker 1.9 even complains that &quot;this image was pulled from a legacy registry.  Important: This registry version will not be supported in future versions of docker.&quot;<p>I just ran a quick test (way off peak time) and Quay was 2.5x slower than Docker Hub for an image built from the same Dockerfile.<p>I&#x27;m looking forward to more usable international service at some point, but right now it just isn&#x27;t really worth it.
