Btw what switch do you have?

There is a known problem in HP switches where traffic from port operating at
Gigabit to port operating at 100 Mbps (or the other way) will be really slow.. 
20-30 Mbps max. Although sometimes the performance is ok.. mostly not.

The problem can be "fixed" by disabling QoS features in the switch..

                                .     .
                              /    -    \
