Hello, I am a Minecraft servers developer and I've been experiencing some lag issues with one of our servers lately. The server itself uses the newest craftbukkit recommended build (1.2.5 R4.0) and runs on a VPS which has 12 Ghz (6x2) Intel(R) Xeon(R) CPU E5645 CPU and 16 gb (DDR3-1333 ECC REG) RAM. Basicily, my server has 50-90 players from morning to night. Everything works just fine then there around 0-60 players, but it starts to lag then server reaches 70-90 (max) players.
