Xorg RAM usage

Hi...when xorg starts it uses 170 Mb of RAM...i dont know if that is normal but it seems a bit to high..what is your RAM usage?

my setup:
xorg 7.5
openbox
wbar
tint2
xorg nv drivers
 
My current Xorg usage is ~39MB, fluxbox ~10MB, firefox ~123MB.
Depends how much memory you have: the more you have the more it used; "free memory" is lost memory.
 
I may be wrong but I think it depends on your X-based applications usage.

I currently have 169M of reserved memory for Xorg.

Where are you getting your memory usage numbers? A lot of people misinterpret top(1).

from top...obviously i have been misinterpreting then :\...how can i found out the real mem usage then?
 
xrestop shows a much lower figure for me. I'm sure top's two memory usage figures (SIZE and RES) must be of relevance still?
 
For example: i get whole top(1) table with `top -bS 1000 > toptest`
Now, i count sum for column SIZE = 3016M
sum for RES = 621M
(note: i have only 512M RAM with nearly 104M swap used)

So about top(1) AFAIK
RES = Process size minus swapped out pages. In other words, this should be exactly "amount of memory(RAM) using by process".
SIZE = Virtual memory used by process. This is RAM used + swap used + shared libs. Note if 2 process share same libs, they will count in both SIZE's, so just sum them is not right.
