I only have performance numbers for the parser right now, and on average it takes about 0.07 milliseconds to parse and validate an address. That's the pure RFC

I only have performance numbers for the parser right now, and on average it takes about 0.07 milliseconds to parse and validate an address. That's the pure RFC syntax part. The longest part of validation service is DNS checks, but once the DNS server warms up and starts caching lookups the roundtrip time is going to be the longest part of the request. We're still collecting reliable statistics and once we have them we can follow up with you.
