Even the mail server is doing double duty :)
The only thing that is still doing what it is intended for is my main webserver, everything else is going flat-out. There is some risk of duplication but I'll take care of that later.
I'm getting nearly 150MBit/sec peak so I really can't complain.
I have to hand it to my provider though, we get transit times that are just about unbelievable, when it's quiet beteen 30 and 50 ms rtt, and when it's busy still under 150. That helps a lot.
