[AccessD] Array faster in DLL?

My brother-in-law, who develops in VB6, has told me that writing his DLL's
in PowerBasic gave him a 10:1 speed improvement. Then, for a couple of
critical ones, he moved to Assembler for another 5:1.

Hi all

I have some routines that manipulate data in and between some arrays. 
The arrays are not large but they are recalculated about 3 mio. times which
runs on my machine to 90 seconds.

I was wondering if there would be any significant speed increase by moving
these routines to a DLL. I have no experience in writing such libraries but
guess I could find as the routines are uncomplicated. Variables are Long
mostly, only one Single. 
It would take me some time to program these, of course, and if the speed
increase only could be expected to be, say, 30%, it wouldn't hardly be worth
it.

Does anyone (Drew, Stuart?) have experience about what to expect?
