Downstream Transfer Speed Clarification

We are evaluating your software - which by the way is VERY nice BTW -
but have a question about transfer speed.

When simply using IIS and its built in directory browsing feature users are getting around 
800-900k. The same file, on the same server using File Vista direct link feature gets 200-300K.
This is a reproducible every time.

Is this typical? I understand there is overhead involved with ASP but I didn't think I would see this much of a speed decrease. The server is a Virtual Machine with about 2GB of ram dedicated and otherwise has nothing loaded on it. We are using Windows Server 2003 x32.

Thanks,
Steve

Hi,
This may be due to the chunked downloading. For minimizing memory consumption, we are using a 8KB buffer for downstreaming the files, ie. we don't load the whole file into memory. It seems this buffer is not enough for best performance. I guess we can increase the performance by increasing the buffer size. I have sent you updated DLLs via email. Please test the speed again after updating the DLLs. I will wait for your feedback.
