I’m running a Nginx web server in a Docker container on a VPS hosted at Hetzner Cloud.
The VPS has a symmetric 600mbit/s connection.
When running my website through CloudFlare, the performance is lacking. Tested with a 1GB test file, which downloads at ~3MB/s when CloudFlare proxy is turned on.
When I turn off the CloudFlare proxy the performance is as I’d expect, maxing out my home connection while downloading the same 1GB test file.
Any ideas what’s going on here? Does Hetzner have bad peering with CloudFlare?
Downloads seem to be capped at 3MB/s, no matter what network I test from.
