Re: [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...
