We next consider server throughput in terms of new connections. In netAuth, although the first authentication must be signed, successive authentications require only a very fast cryptographic hash. From table 1, the service-based verification of signatures takes only 80 microseconds. Hence, a single core can perform authentication for 45,000,000 users per hour assuming authentications are cached for one hour. We believe that such performance levels eliminate the need to consider weaker authentication mechanisms, even for very high volume services.
