Low performance using Win2K DDK to develop driver for Win NT 4.0

Hi,

I’ve a problem that running the same filter driver, which is compiled by
Win2K DDK, under Win NT 4.0/2K/XP get a very huge differences in their
performance. The driver works smoothly under Win 2K and Win XP, but it
works poorly under Win NT 4.0. That is observed by reading a huge file
with and without my filter driver.

Will there be any runtime problem(s) to use Win2K DDK to compile driver
for Win NT ? And, will there be any special optimization methods ?

Thanks a lot.

Are u saying that I have to use Win NT DDK for compilation for Win NT 4.0 ?
But, how can others make a single driver for various platforms ?

Thanks.
