Following reply by iljitsch van Beijnum about queueing delays in IP, looked to be a good little summary. The answer is that delay is only one aspect of performance, another important one is packet loss. As link bandwidth increases, queuing delays decrease proportionally. So if you’re using your 10 Mbps link with average 500 byte

scaling web apps

A little video, thin on detail of course, but hints at some home truths on building/designing scale-able applications (and i'd go so far to say that they are applicable to ALL applications not just webapps) http://joyent.vo.llnwd.net/o25/videos/LinkedIn-Bumpersticker-LED-Scaling-Rails.m4v Of course, I know Ben Rockwood like's his solaris and F5's - but that's not going to surprise many (and I just LOVE f5s) And here's a blog entry with the details on /how/ that's done:- http://www.joyeur.com/2008/04/18/the-wonders-of-fbref-and-irules-serving-pages-from-facebooks-cache . . . basically as simple as:-

when HTTP_REQUEST {
  if { [HTTP::uri] contains "/popular_something/list"} {
    HTTP::respond 200 content "<fb:ref handle='[HTTP::uri]'/>"
  } else { 
    pool facebook.application_server_pool
  }
}

Oh interesting stuff there - I've always liked the idea of FAST (not cheap as a search platform) but they've certainly thought a bit about how to scale - will be interesting to see if this mean's a change to the supported platforms and roadmap moving forward
