I am running a two person server with 3GB out of the 4 on one of my other computers, and it still has a jitterbug with block breaking where they disapear and the item dosent appear for 3-5 seconds after the block is broken, also the entites besides the players rubber band alot... you hit them then they appear 10 blocks away. 3GB is enough for 2 players right? Also it has an ok CPU for servers. Its a Intel Pentium(R) Dual Core clocked at 2.3Ghz which should be fine for 2 players. I dont understand why its not running alot smoother than it is. Thanks in advance. BTW the ram is clocked at 1333 Ghz
