Larry,
I agree that Dpaint is a terrible CPU hog, and in trying your tests, I
find that if the mouse is positioned over the Dpaint screen, whether it is
active or not, Dpaint hogs cycles. With all that said, I have seen situations
where when using an effective 640x400x4 workbench screen plus severe overscan,
even loading a program from the CLI (such as Access! or MetaScope) will show a
marked loss of performance.
Using Dpaint and a ST506 drive, doesn't show near the degradation. Neither
does a floppy. In fact if I set MaxTransfer to 512 in my mountlist, performance
improves dramaticly with all other things being identical.
BTW, the 'problem' is worse if the file is stored contigusly. If it's
scattered on the disk, it loads much faster. (consistant with the MaxTransfer)
Also, with a OFS drive, loads are faster under the same circumstances.
Dpaint is a DOG, the 2090 does have problems as well, although in every
other respect I've been satisfied with it.
