lots of discussion on pooling network resources. In addition, some in depth discussion on how to handle immensely large amount of request - 3 billion per day or higher.

Learnings:

  • Good developers usually are bad DBAs.
  • The bottleneck moves! Once you eliminate one, you're faced with the next one. So it's an iterative process.
  • Getting software and hardware people together from the start is a good idea
  • Cacheing is key: squid, memcached, APC
  • Turn off Apache modules you don't need fo huge performance gains
  • One person's ad serving network was processor bound, because h ad machign queries are complex.
  • The OSL's server farm is i/o bound, because they're serving up static files like ISOs.
  • Participants were intresested in content based load balancing but hd not implemeneted it.
  • Smart load balancing helps - BINDDLZ
  • Round robin DNS works for stateless web queries

    • networking bottlenecks

    I'd like to hear about your network, its components, why you built it the way you did, what you'd like to change. Where are the bottlenecks? Where are you running otu of resources?
