I've got a question about lowering CPU loads, if I understand correctly when I issue the 'uptime' command I get 3 values representing 5, 10 and 15 minutes of average CPU load. My current stats are around: load average: 0.57, 0.72, 1.42 offcourse they fluctuate but the 15min value is always between 1.40-1.80, from what I understand everything above 1.00 is NOT okay. My specs are:

Intel(R) Celeron(R) D CPU 3.20GHz single core processor

1GB Ram, 1GB swap, 512MB zram: Filename Type Size Used Priority /dev/sdb7 partition 3004116 129688 -1 /dev/zram0 partition 480316 2212 100

Kubuntu 12.04 is on a 80GB drive with about 35GB used, this is the OS and programs, all files I work with or download are located on another drive.

When I issue 'top' I can see no big activity from the systems deamons and background processes. Its mostly the browsers, gimp and stuff like eclipse and codeblocks that take up a lot of memory. But I mostly dont run more than 2 programs together anyway. Also I've disabled window animations and effects.

The system also responds, reads and write at a good speed.

So how can I have such a high average? And are there any more tools to get more info and control over CPU processes?

I know I could better switch to Lubuntu for this PC, but like I said before performance is actually quite good. And its very stable so far I've had no big problems. And I'd like to know this when I upgrade to a better system again.

If other people are interested in this subject, there is no ready-made solution for lowering the load average, since its dependant on usage, os, hardware combinations, programs and the way they are used. I think I already made the right steps and have to keep experimenting and updating to kernels that are targeted at low-spec hardware. Here is a little discussion I had from posting this thread at the Ubuntu Forums:

I hope someone will find it usefull.

Thanks for your interest
