You need to install and enable an FTP server (temporarily, you should
remove it after the experiment is completed)

More linux will definately help, but I recommend having a copy of
Knoppix on hand. I've even remastered my own version, with some very
interesting little network utilities on it.

The `errors' counters here is worrying. If you do a file transfer in one
window, run the following command and tell me if you see this counter
increasing as the file is transfered. The errors are also the reason as
to why it's going so slowly, because the dropped packets will cause
the sending and recieving TCP to slow to a crawl as they timeout and
need to retransmit.

watch -n 1 /sbin/ifconfig eth0

If it does, then you can try to either

1) Connect to the switch using a different cable.

2) Connect to a different machine using a crossover cable.

3) Connect to the switch using a different network card.
