Additional instances do not take up more ram because the first instance<br>
pulls the executable page code in to swap space in Unix/Linux. If you<br>
have enough RAM, (and that is critical, or it Unix/Linux will need to page<br>
swap, and there goes the lag game.. This falls on basic design theory for<br>
Unix... You can never have enough ram. You always want to have enough RAM<br>
to run your programs in ram, or you will page swap. Page swap = slow,<br>
without getting in to the nasty details). How can I tell if I am page
swapping?<br>
<br>
run " vmstat". Check the man page for vmstat. You will
see a PI and PO,<br>
these should be zero. If not, you are swapping in pages of code to execute.<br>
Add more ram, and you may have to relink the kernel, but most Unix/Linux<br>
version support up to 4GB or more for 32 bit.<br>
<br>
The way it works is this.... Code for each game will execute in ram, and<br>
share the page, but each will get their OWN data area's for Heap and<br>
Stack.<br>
<br>
However, if one process (Game running) attempts to write to a code<br>
page, Linux will do a "Copy on Fork()". This is viewable in vmstat<br>
as well. Basically it means that "A copy using the shared code
attempted<br>
to modify it, so it make a separate copy for the process that attempted to<br>
write to the code base".<br>
<br>
Since this does not happen in COD, or most processes for that matter,<br>
they all share the same single image in Swap to load to ram, and the<br>
same single image of code in RAM. If you were to put the processes<br>
in debug, and look at the registers, you would see the code segment<br>
registers are all the same, but the data pointer registers are all different.<br>
<br>
Check out vmstat, and read the man page. It is worth your time.<br>
It will give you some good insight on how the resources are allocated...<br>
<br>
Nice huh? Someday Windows will really work like that, or maybe<br>
it will replace windows? {;-))<br>
