I have 6GB RAM, i5 2.4GHZ Processor running Ubuntu 11.10. I partitioned my HD so that I have 8GB swap.
When streaming online or opening several tabs in Chromium I soon have 4GB Memory in the cache. And I think this makes my Notebook slow. When streaming a video, after a few minutes it really slows down and stumbles/jerks.
What could the problem be? How can I solve this?
P.S: initially I had 4GB and recently upgraded to 6GB, but I did not experience a significant change.
free -g in the terminal prints this:
