I never have.

On the other hand, I have now made a lot of tests, and two things
are clear: running in 286 mode is slower than 86 mode. Not just
in Windows, but always. MAybe 5 to 10% slower. 

Second, most people run Windows 2.x in color mode with ***8***
color drivers. The Win 3.0 standard drivers are ***16***  color.
This means that things like BitBlts and icons are slower by some
amount, maybe 4/3, as there is often 4/3 as much work to do.
This seems to account for much of the slowdown. I tried comparing
2.11 and 3.0 in mono mode and they got much closer in speed.

Also, to the person who posted the "4" at 0x437 for getting rid of
the "old version" message: THANKS.
