While NDM process how a 103 MB zip file took just 15 seconds while a normal 103 MB file took longer time to tranfer?

While the size of the files are same, shouldnt the time of NDM also be same? How come the difference?

Hello,

Possibly because of different loads on the sending or receiving side of the transfer or different network loads at the time of the 2 transfers.

If one was a binary transfer of large blocks and the other was a text file transfer of smaller records, that may also contribute.

I'd suggest you run both transfers (multiple times) at a very quiet time on the network/systems and see if the difference is consistent or if it is not predictable.

Also don't forget built in compression in the protocol. If the NDM protocol couldn't compress the 103 MB "normal" file then it should be similar in speed to a zipped file of comparable size.
