Ping shows a consistent response time of 31 ms.

We are suppose to be connected with a "home business" level service.
Just ran a couple of speed tests and found:
(down/up speeds in kbps)
1) Bell Canada: 7912 / 779 (Toronto-based)
2) Rogers: 7850 / 969 (Toronto-based)
3) Speedtest.net: 7890 / 910 (Toronto-based)
4) DSLReports.com: 5222 / 756  (New York-based)

Our internet connection runs into the building and then is managed by
an IPCOP box that acts as our firewall and does caching (Squid) and
filtering (Squidguard).  That then plugs into a 10/100 switch that
then plugs into another 10/100 switch (different floor) where the LTSP
server's Internet network card plugs into.

>From what I can see, we should have more than sufficient Internet
bandwidth so that the bottleneck is not that part, correct?
