Using a brute force timeout of 5-10 seconds should increase the throughput quite significantly without much loss of resolvable hostnames. It's the minute-plus waits on a small proportion of addresses that is the real killer. It seems to be quite dramatic -- I'll try and post the results of a controlled test in a day or three. The delay to defeat the DNS cache. Adding some parallelism would fix it as you say, but it's probably not worth the effort (or system resources). The standard DNS timeouts are hopelessly long on most if not all platforms, IMO. It almosts defeats the idea of adding multiple name servers in resolv.conf -- it takes so long to rollover to the next host that I've normally given up and decided to do something else by then. -- Malcolm Hoar malch@malch.com Kant spell Neetchie
