Wolfram has deleted the files needed but I managed to find them here: http://ubuntuforums.org/showpost.php?p=7486232&postcount=46 I copied the files in both /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Libraries/Linux and /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Libraries/Linux-x86-64 Cpu usage dropped from 28-30& to 1-2% when Mathematica is idle. I've also done what post #48 suggests and deactivated Java Library with chmod a-x /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Links/JLink Hope this helps ;), S~ Thanks a lot man.

I copied the files in both /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Libraries/Linux
and /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Libraries/Linux-x86-64

Cpu usage dropped from 28-30& to 1-2% when Mathematica is idle.

I’ve also done what post #48 suggests and deactivated Java Library with
chmod a-x /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Links/JLink

Hope this helps ;) ,

That is way cool man! The steps weren’t that complicated too, which is great. I love it! That is way cool man! The steps weren’t that complicated too, which is great.
