[K12OSN] Where is the bottleneck?

How are you doing? I hope all is well.
So I was recently informed by one of our staff that our LTSP
(k12Linux) system is too slow for youtube videos. Not being a youtube
person (at least at work!) I had never really tried it so I gave it a
Server -> gigabit card -> gigabit switch -> gigabit client (Dell
Inspiron 530 - Core 2 Duo processor 1 GB RAM)
Ran the test when there was no one else logged into the network. Gave
the Old Spice youtube video a whirl (
http://www.youtube.com/watch?v=owGykVbfgUE ) (ran it at 480p setting)
and it's horrible. It's not a video as much as a fast-flickering
slideshow. Just to put it further I ran it at full-screen mode and it
looked more like a powerpoint slide presentation than a video.
I tried re-running the video several times, to see if having it in
memory/cache made a different but it didn't.
So I'm not sure what is the problem. I recently purchased the gigabit
switch specifically to help speed things up but now I'm very worried.
What do you recommend I do in order to determine the location of the bottleneck?
