File Transfer speed

[Guest_imported]

Newbie question. I'm transfering a 55MB file from my workstation to our server. We're on a 100Mb/s switched network. With little to no traffic, it is taking me anywhere from 20 to 30 seconds to transfer this file. Is this normal. Assuming no overhead, my calculations say that this file transfer should take about 5 seconds at wire speed. Adding for overhead, and other network traffic, even doubling this time is 10seconds. Is this normal, or do I have a bottle neck somewhere?
Thanks.

typical disk I/O is 11 meg a second, so it will take 5 seconds to leave your disk, and 5 seconds to write to the other disk before we start to count the network.

the receiving computer has to send packets saying how much of the file it received, and the packets need to calculate a checksum (CRC) and there is an inter-packet gap, so you do not seem out of control. I tried to remain child-like, all I acheived was childish.
