13 I've been noticing this kind of thing too for a while now. In my case it's the
14 nepomuk/akonadi/virtuoso stack doing it - it seems to trigger full scans at
15 weird times and does other special things after a resume from suspend.
16
17 Virtuoso can sometimes get as high as 800M RES memory in top. Which is all
18 quite bizarre, I suspect a dodgy config on my part.
19
20 As for kwin - what column are you reading the value from? Here kwin uses more
21 like 60M
