For the last ****ing time bandwidth != latency, and server lag usually has very little to do with latency except in extreme cases. The server could be perfect and you might still get 200ms if the network path sucks or you're far enough away. Going from a 5Mb/s to a 20 Mb/s connection could easily result in an extra 20ms latency to some hosts.

That's not to say it's not an issue with the server (but this post will get deleted if I mention what the issue is), but please stop conflating bandwidth and latency.
