FYI, I actually took one of our backends at b-root and performed AXFRs to it to see how much of a days load it could handle for transferring complete copies. Not a fantastic, rigorous test suite, mind you, but the upshot is that one single machine could handle about 1/2 the world's load. Obviously that's not a complete solution, but it did put my mind at ease for the expected load as this was without even trying to optimize anything. With many sources available over multiple protocols, I would be hard pressed believe scaling will be an issue, especially if we pull in many sources and multiple protocols. -- Wes Hardaker Google _______________________________________________ DNSOP mailing list -- [email protected] To unsubscribe send an email to [email protected]
