Server parameters improved ftb to 100% cpu to 10%-20%

[Apuly]

For the people who are wondering, to log file shows the error that occurred which caused the server to run at about 5%. It happened just before loading the default dimensions (also known as overworld). Kil and me aren't 100% sure what it does, or what caused it, but if you were able to recreate it, you should be able to run most minecraft servers at about 5% cpu usage.
