This proposal doubles the default number of IPs and reduces the “cost" of being an IP since the probability of being selected is no longer bandwidth-weighted. Is this a fair tradeoff for the performance improvement?
That seems easy to fix. Make the number of Introduction Points the same as it was before and make them be selected in a bandwidth-weight way. There is no cost to this. You need IPs to be online, and so whatever number was used in the past will yield the same availability now. And bandwidth-weighting should actually improve both performance and security.
I think bandwidth weight isn't appropriate for this. If we think the cost of running a HSDir(+IP) is too low, we should increase that directly. This is a good case where we can benefit from the many honest-but-not-well-funded relays. Concentrating even more traffic and information onto the highest-bandwidth relays isn’t an improvement.
