Link Aggregation is a bit like having multiple cores in a CPU. It  
allows you to do more things simultaneously, but any one thing is  
still limited by the speed of a single core or ethernet link. The file  
you're transferring is probably only utilising one of the available  
links.

For this reason, Link Aggregation is generally more useful on servers  
which interact with many clients simultaneously.

Cheers,
TB
