I was over on Free SunnyD today, and was horrified to see that it was so badly set up that it was virtually unplayable.
First of all, gravity was WAY too high, making it virtually impossible to navigate even slightly rough terrain. Some of the maps have bumpy terrain, and what were normally little bumps to jump over became insurpassable obstacles! This is, quite honestly, stupid. Set the gravity back to normal!
The second problem is in the server's network setup. The sv_maxrate seems to be way too low, as I was getting mad choke at anything over cl_updaterate 20. Even setting it down to 20 wasn't enough; while this eliminated most of the choke (Was still seeing 20% choke even at cl_updaterate 20), the server was still laggy as hell.
To be honest, trying to play on the server was so frustrating due to the incredible lag and rediculous gravity, that I will not be playing on Free SunnyD until it is resolved. Until then, regular Lunixmonster NS and non-broken SourceForts servers for me
