The point is that the main problem here is not the network bandwidth but the
disk I/O resulting from the enormous size of the data. This is similar to
your desktop machine with 512 MB memory when you open and use so many
applications at the same time that they use 3 GB if memory. In that case the
machine starts swapping in and out memory pages resulting in a real slow
system.
