Bumping this to save making a new thread. I've posted on VM's forum but despite virtually every thread on page 1 of their speed forum getting a staff reply in the last 24 hours, mine was ignored.

I'm still experiencing throttling of OpenVPN on multiple providers. If I connect to OpenVPN over UDP on port 443 (for example) I can barely manage 5MB/sec even on Ubuntu torrents (always exceptionally well seeded and can max practically any line). As soon as I further hide my OpenVPN connection inside an additional SSL layer (i.e. tunnel the tunnel by wrapping OpenVPN inside SSL) voilà! I'm back to 18MB/sec without issues.

VM are adamant they don't throttle or shape VPN traffic, but if that's true why does ADDING an extra layer of encryption (which should lose me speed) give me a 400% increase in throughput and allow me to max my line where plain OpenVPN to the same provider and the same server failed?

Anyone got any input? I'm seriously thinking of switching to FTTC from Plusnet or Sky or whatever. I can see the cab from my door and the checker reckons I'll get as close to 80/20 as makes no difference. I'd rather have 100% of 80Mbps than 25% of 152Mbps. Plus, that upstream...
