If I write a hardware interrupt driver for OS2 how many interrupt can I
expect being able to service. How much more overhead does OS2 impose
on hardware interrups? Finally what kind of performance degradation 
will I see for may hardware interrupt handlers moving them from DOS to 
OS2? 

I have heard a limit of 1000 interrupts being the maximum? Is is this for 
virtual interrupts (for DOS program running on a virtual DOS box or does
this applies as well to OS2 harware interrupt handelers)? Is there an
IBM statement on this somewhere?


Thanks, I have to convice superiors that going to OS2 should not cause a 
serious performance problem. Right now the DOS version handles somewhere 
between 4000 and 5000 interrupts per second and the must still do it 
under OS2.
