Not really, no. I did discover that I hadn't maxed out my newsgroup connection limit on this container to 50, however. At this point I'm getting around 25-30MB/s with two newsgroup connections. This is with PIA running off the US-Chicago (OVPN) server which was the fastest for me.
I did test all of the US and Canada servers as I am in North America. For me, the fastest were Washington DC at 14, US East at 15, and Chicago at 15. Believe it or not Venezuela also came in at 15 but most of the European connections I tried were slower. All of these speeds seem to be per newsgroup, so I tried a third server but was unable to increase my speeds.
I am not running Wireguard as that config didn't seem to increase my speeds at all and I have yet to try another provider at this point.
If anyone is getting better speeds with PIA or another provider and care to share how they've got it configured I'm all ears!
