RScripts

Hello, I have a bot running on my VPS, which has 2GB Ram and 3.4GHz Quad Core Processor. Ive tried running it without a command for 1gb Ram ( java -jar -Xmx1024m 0sb*.jar ), its gets around 5-10FPS normally, Ive also tried it with the comand stated earlier and get the same result, Im using the script Notori-planker. Occasically the FPS jumps up to around 40, then drops backdown, do you think it could be soemthign to do with the script? Any help is appreciated!
