Slow Container Upload Speeds

I've spent some time in on this issue and I'm at a loss. I'm attempting to host a music bot using a container running Ubuntu 20.04 (also tested on Debian 10). The music is choppy but the host has plenty of resources. I've tried three different bots and they all have the same issue which then led me to verifying networking performance. My home speeds are `900Mbs/35Mbps` and I stream on Twitch occasionally without issue or dropped frames. This server also hosts several Minecraft servers in a VM and users don't seem to have an issue except when I saturate my connections while they're online.


Below are the various test results I've attempted and I just can't seem to figure it where the issue is. I can post any logs that are requested but please let me know how to obtain them as I am still new to Linux as whole.

this test shows that the network generally reaches high speeds which means that it seems the choppiness stems not from the network


Container to iperf.scottlinux.com
i also get here only 10mbit/s (from my host) so it seems the connection there is not really fast

all in all, i'd either check (e.g. with iperf) the connection between the server and the actual client where you stream
or try to debug this on an application level instead

Is there any other tests I can check? Also it seem when I'm saturating my connection to one VM the others seem to have issue with network connectivity.

Alright that seems pretty standard from other people that have tested so I'm not to terribly worried.

I wish I had the ability to check latency with Discord but I'll look around. Thank you for your response.
