Edward, I have about the same size network as you do, about 1850 now, and
I've found that checking your logs and watching for errors/timeouts and
resolving those increases the time dramatically.  I've read that 1900's are
slow with netdisco, but fortunately, I have only a couple of these on the
network.

My arpnip takes 110 minutes, discover takes 615 minutes and macsuck takes
300 minutes as a comparison.

Hi,

I have a large network with about 1700 entries in the device table
(using netdisco 0.93).  It is taking about 9 hours to perform an
arpnip (-a), 9 hours to perform a refresh (-R), and about 12 hours
to perform a macsuck (-m).  Is here something I can do to reduce
these times?

I was wondering if netdisco could be made to poll several devices
in parallel.  I would think that this would help with the arpnip,
macsuck, and refresh/discover processes.

Also, with so many devices, the network map is a virtual blob.  Is
there someway that the map could be made into layers or sections to
make it more readable?
