I have a Pi running Raspbmc by the TV and a desktop computer in the study. For a while, I had the TP-Link gigabit router next to the Pi and the desktop connected via household wired network cables. The household network was poorly configured and only getting 10Mbps speeds. I redid the network outlets making them gigabit-capable and moved the router into the study. Now I get 100Mbps speeds as measured by `iperf` (the Pi only supports 100Mbps). But for some reason Raspbmc's networking has become slower! Before, when I started a video it would spin up in a second or two. Now it takes 15 to 30 seconds. And if I try to switch to another video while one video is playing, playback stutters and slows down to nearly a halt.

Could the Pi's networking slow down because of its distance from the router? This is the only explanation I can think of, because nothing else has changed other than the router location and the added support for 1000BASE-T in the wiring.

To be clear about the wiring, previously the house was wired with only 2 twisted pairs being used per port. Being only [10BASE-T](https://en.wikipedia.org/wiki/10BASE-T) the maximum speed was 10Mbps. I rewired/recapped all the network cables so they now use all 4 twisted pairs and support gigabit speeds. I confirmed gigabit is working between two computers that have gigabit support. The Pi only has 100Mb support which I also confirmed is working.

EDIT: output of `ifconfig`:
