[K12OSN] Looking for video performance solutions

Ahh yes, that looks like the problem. I forgot when the server moved,
the link changed from a local site being 100 to a 10 Base over fiber. I
just tested at the new site where the server is and much better on the
10/100 network.
So our 3 fiber uplinks to other buildings will have to be upgraded most
likely. At the same time I know the director of technology's vision is
to have 4-5 terminals per classroom which will help justify upgrading
the backbone hardware to a gigabit solution. Probably looking at
implementing around 250 terminals at our Alternative, Middle, and High
School District.
What's the ratios usually to client per server - 50 terminals per
server?
Anyway, just some side notes, but thanks for the feedback...
