  • What OS are you running?
Windows 7 x64
  • Are you using minecraft hosting provider or a dedicated/local server not designed for minecraft?
Using an old but fairly decent laptop to host - on all the time, connected to our home network.
  • What version of FTB are you using? (Dont just say latest tell us the version)
1.4.7
  • Did you add any mods to the server pack?
No - we (the players) have added optifine on our side, but I don't believe that should affect the server side of things
  • What are your server specs?
Windows 7 Professional, Service Pack 1
Intel Core i5 M540 @ 2.53 GHz
4gb RAM (out of which, I've given the server 1gb and it only ever uses about 15-20% of that, even when it's lagging)
  • A good detailed paragraph about the problem
OK! Server was running fine. Well, I've been having some random client-side issues I guess but those weren't a big deal and didn't seem to be server related. Got most of my lag issues ironed out through messing with Optifine settings. So, two days ago is when the trouble started. I went to try to log on and found that the computer had restarted for some reason, so I went upstairs to the server room to turn it back on. Got the server started up, everything seems like it's going fine, go back down to my room to log on... and there's massive amounts of lag. I can't track down a reason. Restarted, closed all the extra shit my roommate had running on it, nothing helps. Tried restarting the router, nothing. I'm the only one who's been on for the past day or two, and all I was doing the day before the lag started was exploring the twilight forest. I transformed some cows and pigs and chickens in the "normal" dimension that day, into deer/wild boar/penguins, but I only have 2-4 of each so I don't know why that would be doing anything.

ANYWAY. I did some poking around and found out about the debug profiler thing. I've ran it but the results mean nothing to me.
Attached please find both the profiler results as well as the STDOUT server log for what I believe is the relevant time period. Any help would be greatly appreciated![DOUBLEPOST=1368815271][/DOUBLEPOST]Oh, hold on, I just figured out how to do this:

Code:
---- Minecraft Profiler Results ----
// Am I not running fast enough? :(
 
Time span: 173717 ms
Tick span: 1063 ticks
// This is approximately 6.12 ticks per second. It should be 20 ticks per second
