My overall analysis is that one 1Gbps relay is a better contribution to
the network than two 100 Mbps relays, assuming other variables are held
constant. This choice by a single operator isn't a significant impact
on security or stability, but in general we want
- more operators
- more AS diversity as share of exit bandwidth
- more bandwidth
- more nodes
in approximately that order of importance. You're already nailing it on
the first (thanks again!), I think you're not considering to add another
AS (your new node would be on the same ISP), so it's mostly just a
choice between 200 mbps and 1gbps, and a choice between one descriptor
in the consensus or two descriptors.
Also, if we were very short of nodes, then adding more nodes would be a
higher priority; but currently we seem to be more short of skilled and
motivated operators, rather than node-limited.
