That is because the Netgear GS105 is a known piece or garbage.
Try forcing your NICs to run at 100. It will run faster. I just saw it
happen last week.

Tried this - it didn't seem to work. However, Netgear have now said
that their switches will always run at the speed of the slowest device
on the network (or possibly, directly on the switch). In my case this
would be 10Mbps because I have a networked printer (or 100 Mbps if
it's only connections to the switch which affect it). Surely this
rather defeats the object of having autosensing ports and cannot be
regarded as "normal" behaviour?
Thanks,

The actual download speed is throughput(time)= file size/bandwidth. Which
is kilobits not bytes. Actual bandwidth (because of contention and media)
is never stated bandwidth.
