I already have Forgejo installed and found out it does basic Oauth2. I didn’t have to do anything. It just worked out of the box.

There is probably something wrong with your setup, if Synapse has these problems.

I’ve been running Synapse for years, including voice/videocalls and even video conferences.

Did you use iperf? It makes sure that HDD/SSD is not the bottleneck.

You can also check the statistics and watch for uncommon errors. Or trace the connection with tcpdump.
