First of all, before presenting the problem, I just want to say that i´ve really been struggling and searching everywhere and tested every possible solution but it all keeps failing on me.

Me and 2 buddies are trying to set up a small server to play FTB Unleashed (1.5.2), we have tried their old spare computers but they had excess lag so now when i bought a new comp. for myself i thought i´d use the old one as a server since it was the fastest of the 3 but the same issue there, loads of lag! Previously we ran FTB Ultimate on one of my buddies comps with the worst specs without much problems)

Computer/Specs
AMD Athlon64 X2 6000+, 3.1Ghz
4GB DDR2 800MHz
Broadband speed tests result in ~90Mbps up and down.
Firewalls disabled, IPV6 disabled

Im getting the "Server cant keep up" message even when loading a completely new world with 0 players.
The computer is completely wiped with a fresh installation of windows7 64-bit, 64-bit java and FTB unleashed server, thats it!
The script im running to start the server is
Code:
java -Xms512M -Xmx2G -XX:PermSize=128m -jar ftbserver.jar nogui

The weird thing is that when im running without the nogui (so i can see the server ticks) my avg. ticks bounce between 3ms and 30ms, even when there is absolutely nothing going on on the server, i mean, no one has even ever logged in to it so i really mean nothing!

Im clueless, is the answer that the CPU and RAM are to slow? Is Unleashed a crazy resource hog? Or is there something i failed to grasp when setting up a server for FTB?

Any ideas are welcome!
