About This Computer

I am using GNU Image Manipulation Program version 2.8.14 on Ubuntu 14.10 x64 on
my AMD Phonom II X4 machine packed with 8GB DDR3 RAM and more than the
recommended amount of SWAP-Space found in multiple locations throughout my PC,
and even though I have all this caching space and more plus a powerful
processor, GIMP still eats my computer's system resources alive even while
doing some quick editing and touch-ups, specifically when using the Heal tool -
The window will freeze up and continue what it's doing in the background, but
for that time being, it won't let me do much besides that.

It has now gotten to a point where GIMP uses so many system resources all at
one time where it locks up my (USB 2.0) keyboard for all apps and won't let me
use the keyboard at all until GIMP is done doing what it is doing.

I have even switched to the LowLatency Linux Kernel to help speed up my PC and
keep only needed background tasks while using minimal RAM.

See below for a HardInfo chart I pasted stating my Operating System
