I've got 1000/50 service from a mid-size ISP. It's pretty consistent- any time I run a speed test from home, it will hit those numbers. I have an opnsense plugin checking twice a day.
Performance from my self-hosted services to the internet, however, is very inconsistent. Sometimes I get the full 50, sometimes it will only hit 5 Mbit/s.
Is it possible a VPS proxy could provide less congested routes? Is there a better way to troubleshoot the bottleneck? When i notice a slowdown, usually watching a clip on frigate, I'll use a public speedtest to check my field connection. If it's over 50 down, I'll check librespeed on my server. If frigate or plex is fast, librespeed will be too. If I've noticed a problem, librespeed has always agreed.
My host machine is a 5700g w/ 64 gigs of ram, X520 nic to an S33 modem, so I don't think it's a hardware bottleneck.
It's not the connector that's the problem with EA stations and the like, it's the total absence of maintenance. I for one appreciate CCS1 and J1772's simplicity of implementation. NACS was designed by a marketing team which means far more complexity behind the scenes. They've done well keeping their stations running but the pins and sockets only matter for the sales brochure.
