I'd expect that transfer of 12MB to go in something like 18 seconds or
so, not minutes!
A good network card can get as high as 900 odd KB/s over cheapernet
(10Mbps simplex) with the cheap 'n' cheerful types getting 650 to 750
KB/s transfer speeds.

Of course, this depends on how many files make up the 12MB of data. One
or two files might go in as little as 15 seconds whereas thousands of
files might well slow things down to minutes rather than seconds. How
many files were you transfering?
