I've solved pure netflow problems with 150,000 nodes very quickly.
It's always worked well for me.
Could you have inadvertently included a non-arc variable?
Side constraints slow the network simplex considerably.

Thanks for the reply, Doug. Unfortunately I've tried the problem using Proc
Netflow and it didn't seem to scale very well -- it worked OK for a small
sample problem, but can't seem to handle the "real world" problem I need it
for. Maybe I'm fooling myself to think coding it by hand in SAS would be
better, but the alternative seems to be C or C++, which I'd rather not get
into if it can be done in SAS.
