Mike and me were talking about outgoing connection count, not incoming,
which is another thing entirely.
However, to your point: having 1000 Bitcoin connection is still almost
no traffic, the only timt you really hit much traffic is when you get a
peer with a client who doesn't have the full chain as they will start
downloading the chain maxing your bandwidth. My bandwidth of Bitcoin is
something like avg 3GB/month for 125 connections which is nothing.
However it has very brief spikes of my entire outgoing bandwidth.
Thus, neither bandwidth nor connection count are really good metrics for
choosing your number of incoming slots.
