Hey Gang,
I have just bought a DX4-100 with 32 Mb of memory. I have a 2 MB ram
disk, an 8 MB windows 3.1 disk cache, and presumably 21 MB laying
around completely unused.
When I run my Fractal generation program with small X and Y coordinates
(800 X 60), it runs almost instantly. There is a point at which the
time required to run becomes MUCH greater than than the total number of
points. Examing what was happening, I noticed that the disk drive was
thrashing about.
800 X 600 X 4 floats/pixel X 2 Bytes/float -> 3.84 MB
I should have much more memory than I need to run the entire job in
memory, and yet I appear to be paging and/or swapping.
I use himem.sys, windows ramdrive and smartdrv. I have all extended and
no expanded memory.
What can I do to use all of my memory and never touch my disk?
Thanks,
Brian P. Barnes
