Question : Why is uploading through CF so SLOW compared to an ISAPI DLL?

I've been successfully uploading files via CF for many years, and recently a found an opensource ISAPI dll for uploading:

http://www.codeproject.com/asp/upload.asp

It turns out that an 80MB file that takes 20 minutes to upload using CFMX takes on 50 SECONDS using this DLL solution.  I've been on the slow boat for years and never knew it.

WHY is CF so stinking slow receiving files - what would it be doing that is so different?  I'm sure it's something simple, but I can't see it.  I've tested it using ASP and it was even slower.

I'm looking for someone that can show me how to speed up this process.  I'm sure it's something in the header that is specifing a chunck size or something, but I am spinning my wheels.

Ideas???

Thanks!
