Sorry to disappoint you: I don't think our opinions are biased in this
case.  I have hard data to support what I wrote.

I would guess that your system setup with CWSDPMI is far from
optimal.  Perhaps you don't have a disk cache installed (Windows 9X
installs a cache by default, but DOS doesn't).  See section 3.9 of the
DJGPP FAQ list, for advice about optimal system setup.

My measurements indicate that a given job runs about 40% slower on
Windows than on DOS, on the same machine.  However, I don't claim that
Windows DPMI host is slower by 40%, because I suspect most of the
slow-down has nothing to do with the DPMI services, but rather with
the other system processes that run in parallel.
