I'm playing in a server of a friend of a friend and I'm having a really bad lagging issue where every few seconds my CPU process would spike from around 40%-50% to about 70%-100%. Task Manager even runs a red box on the CPU process. This would last for about a second or two then goes back to normal. I have no idea what's causing this, I have both version of Java installed (x32 and x64). Even my tech friends have no clue why it's happening. I am using Windows 8, x64 Bit with 4GB Ram and the JVM argurments I was told to put in were -Xms512M and -Xmx1G. Streaming a video would make CPU process run as high as 30% but that's it. Minecraft seems to exhaust all of the CPU resource I have left. My memory even runs at 95% or above when playing Minecraft but I don't know if that's normal when running games.

I've tried what you said. No avail. I'm thinking right now it has more to do with Java than it has to do with the settings. Why does it suddenly sky rocket about 10%++ or more after some seconds or even reach 100% CPU Resource usage..

This reminded me of Carly Rae Jepsen's song "Call Me Maybe". the title I mean.

use less ram a lot less

here is what I used for my server it runs fine and smooth now
