I'd be suspicious of that computer. Playing a song and displaying that desktop... and it's got 27% CPU and 54% RAM in use? Clearly hiding something.
Maybe it's just ~reeeeeeeally~ old? :p
Both somewhat right, I guess.
Well, my processor is an Intel Core2 Quad, running at ~3Ghz (a staggering 4799.88
BogoMIPS per core) so that is fairly decent, but I only have 2GB of RAM. Also, I was running a fair bit of software at the time (as usual):
Firefox (memory hog with ~80 open tabs),
Freenet (which is a real CPU hug, easily ends up using a complete core just for itself) and
MySQL. Also my favourite lightweight programs:
WeeChat,
vim and, last but not least,
ncmpcpp. Of course, also a huge amount of processes because, even though I'm a
Gentoo user, I'm doing minimal all wrong
