Hi,

I have created a c++ based XLL which I use within Excel. The code in
the XLL is fairly computationally intensive and uses old 'c' style
calloc type declarations to assign dynamic memory. Unfortunately, I see
dramatic difference is performance between running the XLL on a
machine with NT (service pack 4) operating system and using a machine
with XP or Win 2K. The difference is performance is amazing .. it can
be 50 or 60 times quicker on the XP/Win2K OS.

Any thoughts would be appreciated?

Thxs,
F.

If you don't get an answer here, I suggest that you post in the
microsoft.public.excel.sdk newsgroup.
