Hello,
=20
We are developing a communication program and we are using DJGPP =
compiler, that software needs to run in DOS so we are using CWSDPMI too.
=20
In the software we need to use enable and disable routines a lot with 31 =
interrupt, so my program run very slowly.=20
=20
I profiled my program with gprof and found that =
__dpmi_get_and_enable_virtual_interrupt_state uses 100% of the time, I =
read the BUGS file about CWSDPMI and found that Int 31 causes poor =
interrupt latency.
=20
How can solve my problem?
=20
P.S. When I run my program under Windows 95 It is very very fast. Are =
there any other DPMI server that could I use?
=20
