At first I thought it was the daily cron jobs, but it's been at it for like 3 or 4 hours. It's driving me crazy locking up my system. I suppose I should get off the computer anyway, no real reason to be on for so long.

The only things that look weird in system monitor is kwin, virtuoso-t and X seems to be higher CPU usage than it should. And CPU usage is 20-50% when I'm not doing anything.

Any ideas?

Nevermind. It was indexing my files.

On a occasion, i'd like to rise the same question again. Lm-profiler in my laptop shows disk activity after every 5 second when on AC:

Write accesses at 563/600 in lm-profiler run: +jbd2/sda1-8
Write accesses at 568/600 in lm-profiler run: +jbd2/sda1-8
Write accesses at 573/600 in lm-profiler run: +jbd2/sda1-8
Write accesses at 578/600 in lm-profiler run: +jbd2/sda1-8
Write accesses at 583/600 in lm-profiler run: +jbd2/sda1-8
Write accesses at 588/600 in lm-profiler run: +jbd2/sda1-8
Write accesses at 593/600 in lm-profiler run: +jbd2/sda1-8
Write accesses at 598/600 in lm-profiler run: +jbd2/sda1-8

as i understand this is some kind of ext4 filesystem polling, but how can i manually decrease(or should i say increase? ) the rate. I have partitions mounted with 'noatime' mount option.
