Thanks for the report! I remember hearing something similar some time ago, but there were no concrete results at the time. We haven't noticed a slowdown from using HTTP/2, but we are also using HAProxy in our deployments, not Nginx. When looking for information on this, one can find many similar reports, for example:
It seems as if the default configuration for HTTP/2 on Nginx is not optimized for uploads. So this is not a bug in tusd, but rather the result of a missing configuration, as some people report tuning the configuration helped improve upload speed.
The last link from above also links to a CloudFlare article, which dives into the topic of upload speed with HTTP/2. I haven't read it fully yet, but it seems as if it provides some potential hints to optimize upload speed. I want to look more into this, but maybe you can also read into it a bit.
Describe the bug The given nginx configuration in the official docs - nginx.conf slows down uploads over https. I setup tusd on my virtual machine and after proxying it through nginx, I noticed significant drop in upload speeds (a factor of 20). Initially I thought that it was happening due to some issue in ssl encryption or proxy buffering by nginx. But, after a bit of experimenting, it turned out that this line was the root cause -
listen 443 http2 ssl;
The 'http2' configuration slowed down the uploads by a huge factor. Once I removed it, the speeds were back to normal again, as fast as on http. Not sure if anyone else has faced this issue, but I thought it would be helpful for anyone running into this.To Reproduce Steps to reproduce the behavior:
