openbox using lot of ram + hotkeys

hello guys i have recently installed arch linux with just openbox and tint2. i have heard that openbox is a light desktop enviroment but at boot it uses about 300 mb of ram and it seems alot to me. here is my htop output:http://imagebin.org/132393

i am also trying to get alt+F2 hotkeys to open gmrun so i added this to the openbox config file:


<keybind key="C-F2">
<action name="Execute">
<startupnotify>
<enabled>true</enabled>
<name>gmrun</name>
</startupnotify>
<command>gmrun</command>
</action>
</keybind>
</keyboard>
seems it doesnt work tho. thanx

In your image, Openbox is using approximately 8MB RAM.

You're binding Control-F2 instead of Alt-F2.

Code:

<keybind key="A-F2">

no but i ment the total amount of ram used seems to me a little high.its basically a clean instsall with no apps

Firefox and X comprise a big chunk of that 300MB. If the memory is available (and you have 4GB) then most apps will use what they can. It doesn't make sense for the kernel to constantly free the RAM when it doesn't need to, that would actually slow your PC down quite a bit.

I wouldn't worry unless you see well over 50% of your RAM being used and quite a bit of disk swapping. In that image your RAM usage was 10% and swap at 0%.
