Don't confuse megabits and megabytes.  You state both in the above.

Look at <http://www.aplawrence.com/Words/2003_09_19.html> for a simple 
description.

5megabytes * 8bits-per-byte = 40megabits.

 From your description you are transfering about 40megabits of data 
per second which is close to the maximum of some harddrives.  I would 
say that your network card is working at 100Mbits per second.  You may 
be running into hardware limitations as well.

There is overhead in working on a 100Base-TX network that will use up 
extra bandwidth so a 10meg file may actually use 12meg of bandwidth.

I have used a program called Netpipe to test network speeds.  I havn't 
seen an rpm for it yet.
