There seems to be a huge performance difference of Junko's huffman compression code on Win2K vs. use on Win9x. When I run it on Win2K for output to the floppy drive, it requires about 1.5 to twice as much time to complete when running on Win2K! What's the time profiling command? Maybe I should try that. Can anybody discern what might be the cause and the fix? Thanks, ck

I'm just not sure if it's a software (OS) or hardware (floppy drive) problem... or how to check on that. Well, I've got Win2K on another PC... I'll try the test on that PC and figure it out. Thanks, ck

Ck, I use both win 2K and win 98 at work and 2K takes longer to read and write floppies in all cases--and the longer the write would be in 98, the bigger the difference. -- Mike Nelson ----- Original Message ----- From: "C.
