When I'm using Firefox, I cannot get >6G down/3G up with my OST server on my Synology RS1221+. With Chrome, I get 9.7/9G down/up.
I filed a bug report with Mozilla: https://bugzilla.mozilla.org/show_bug.cgi?id=1939152
Not sure if there is an issue with OST encoding that could be tweaked to help. Looking at macOS Activity Monitor, Firefox is using a lot of cores with my M1 Max Mac Studio.
