Perspective on memory
« on: December 23, 2011, 09:20:39 AM »
I measured how much ram jwm used - 9.7mb - but what surprised me is that 9mb of that is my wallpaper ;)

Brings things to perspective.

That's the price of choosing "form" over "function".

9MB wallpaper??  Interesting, is that one incredibly high resolution picture or many smaller pics all loaded without being used I wonder?

1920x1200 unpacked (1920x1200x4 = 9mb), as it needs to be for X. I'm not that familiar with X, but I suppose it can be either kept in memory by X (ie. when set by hsetroot) or by the WM (when the wm is known to be running for the session).

Am I missing something? 1920x1200x4 = 9Mb (Megabits), ((1920x1200x4)/8) = ~1.2MB) (Megabytes)

It's the 4 (bytes), which already has that conversion. In bits it would be 32.

Hi curaga
Oh, I see, you are running 1920x1200x32 resolution.
