[K12OSN] Where is the bottleneck?

I have been supporting public schools w LTSP and LDAP for 6 years (about to
start the 7th year). For the first three years, we ran LTSP. At the
beginning of the 4th year, we went to LDAP for exactly the reasons you cite
here, namely lagging across the network. I am only a level one sys admin
(I'm actually a lawyer in my day job), but I'm pretty sure the real sys
admins chose LDAP because it was more efficient to push some of the load
onto the clients rather than have the dervers bear so much of the brunt.

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
K12OSN mailing list
K12OSN at redhat.com
