File transfer rate: What’s going on here?

Posted in Tech by Mythokia on June 9th, 2008

I’m completely puzzled by this. Transferring a file across the network (GigE), a file that contains real data moves much slower (it’s almost a 10 MB/s difference!) than a test file created by fsutil. As far as I know, and I maybe wrong here, the content of a file shouldn’t matter when transferring across the network as the protocols involved (TCP and Samba) doesn’t do any compression on its own. Explanations anyone?
