Thanks for the reply.
Does it mean that at least I create 100 vncserver easily ( 1280 x 1024
with full color) in a 500 MB server.
NO! For the display memory only, the use is 4 * 1280 * 1024 = 5242880
Bytes = 5120 KBytes = 5 MBytes. This is used for the display memory
only. Xvnc (the binary started from vncserver) also needs space for its
binary and other variables. It incorporates a complete X11 server.
If you start vncserver, it starts a tiny window manager that also uses
some memory. In there, you most likely want to do something so you might
want to start an application. The windowmanager and other applications
do need their space too.

Hi,
I want to know how much a vncserver process usage of memory? How can i
measure that? Is it same on Solaris? Can vnc server affect other system
processes if memory usage is high? or in another way?
On m$windows machines and unix machines where it forwards the console,
vncserver is relative small since its main job is to read the display
memory and forward that to the viewer.
On unix machines, where vnc provides a fresh display, the display memory
is entirely in program memory. Then it is a complete (however minimal)
X11 server so it is definitly larger. For 1024 x 768 pixels and 8 bits
colordepth, I'd say it uses a megabyte memory. With 1280 x 1024 and
fullcolor, it uses more than 5 MByte for the display memory only. Since
it is a complete new display, you must add all programs that make the
session like the desktop manager (kde, gnome, cde), the window manager
and such. They also have their footprint which might be based on the
display size and colordepth.
Lot's of question because this is my first mail to the group and i am
the newest member.. i guess ;-)
Just read the list, and if you have a question: one question per message
and a clear subject.
