Public bug reported:
My current HTPC use to always be around 50% ram used since I built it
almost 2 years ago and now it hovering around 95% to 99%. I really
notice this on my laptop before I upgraded my ram from 1G to 4Gb.
Something has changed with 10.04.
there seems to be an issue system wide with caching
mythfrontend for my only uses 20% of my ram
mythbackend 2.4%
mysql 1.5%
Xorg 4%
my laptop
Code:
