In a 10Mb environ, what the heck! I would speculate that double-up won't
make an ROI out of consolidation.
However, this brings up a nasty little problem I'm looking at, and I might
phrase this another way. "How many cascaded switching devices can exist in a

If the reason for the second switch is you ran out of ports, replacing
it with a larger switch is fine if money in no object or you have
another use for these two switches. Otherwise I wouldn't worry, the
latency, though measurable is nothing to worry about compared to your
Internet connection.
Do you know if there was a reason for Switch 3 being in the design? That's
what I would try to find out
Maybe it was necessary because Switch 2 is located in a wiring closet,
whereas Switch 3 and the Wireless Bridge are in the main distribution

In the topology given, the real bottleneck is the wireless bridge ( assuming
11 meg shared ), and of course the ISP link speed.
the switch to switch latency is not the killer here.
other factors are numbers of users, especially the numbers crossing the
wireless link. These suckers still tend to

Although most of the latency comes from your wireless link and the ISP
connection, it still doesn't mean you shouldn't optimize the setup a bit.
You mentioned in a later email that the reason for switch2 and 3 is that
they needed more ports. That's fine, and there's nothing wrong with that
