Kernel parameters...

A colleague of mine is using Template Graphics' FIGARO, a mostly
PHIGS-compliant graphics library on a 3030 with 12MB of RAM. He is
working on porting a graphics program that evidently uses a lot of
phigs-structure-related storage for large images (I know little if anything
about phigs or the actual memory requirements of his program).
The problem he is having is with speed - or the lack thereof. When it comes
time to display the images on the screen (composed of many filled polygons)
the display is fast as all get-out. However, before it can display, the
system evidently has to do some moving of things around in memory. During
this time the light on the swap device goes mad for a while and when it
settles down, the image practically flashes onto the screen.
I would tend to think that his program was hitting some kind of limit
to the amount of physical memory a user process is allowed to use - or is it?
Is there some kind of kernel parameter or the like that you can modify
to fix this if this is the problem? I find it hard to believe that the
person's program would be using up a majority of the 12mb of ram, so this
would seem to be the logical explanation. Any suggestions?
Thanks in advance!
