Hey, just wanted to bump this thread, because I'm also experiencing this issue and would love for this to be fixed.
Background: Linux (Ubuntu 12.04) home server with a C2D E6300, 2GB ram, running only Minecraft and 6 players max. New map with vanilla 1.7.4. Our last map was on vanilla 1.5.2 and did not have any problems. The server even ran two maps at the same time no problem 🙂
Using Oracle's Java (1.7.0 u45) and the lag is crazy. CPU usage spikes. The lag is most prominent when the players are scattered/exploring - even two players 500 blocks away from eachother will cause lag. "Running x ms behind, skipping y tick(s)" etc. With three players far apart, it's barely playable... If all six of us are just hanging at the spawn, the lag is non-existant. I read Kris Cloutier's description and it sounds similar to what we're experiencing.
I'm happy to provide any extra info that you might need! We would very much like to get this fixed, because - despite the crashing & lag - we've made a pretty awesome world. Would be very sad to leave it behind.
PS. I was previously running OpenJDK, since it was working beautifully from beta to 1.5.2, but with 1.7.4 it led to constant OutOfMemory crashes; at some point, the server process would hog all the available memory for no apparent reason. Even with 1 player just sorting the item boxes. At this point, I couldn't even SSH to the server. After hogging all the memory, the process would slowly fill the swap, too - and after that, some other process usually ordered the kernel to kill the server process and thus the server crashed. This happened over ten times a day.
