First off, the DVD-ROM drive in my main work desktop is dead. Second off, the DVD-ROM drive in my laptop is dead. (I'm noticing a pattern here... I'm blaming the power in the building. >_>)
Anyway, so I pop the DVD into another machine and copy 1.7 GB of installers onto my main machine over the network. I then start to install it and realize it's the wrong version!
So then I get to copy 3.25 GB of data over for the CORRECT version. Ow.
The fun thing is I think the bottleneck was still the DVD-ROM drive, not network speeds. Gigabit Ethernet is fun! (Although both machines are only using 100MBit cards, but it means that I wasn't bogging the network down.)
Oh well - installing the correct version now.
