The performance of the network underlying our applications can have a
dramatic effect on the experience of our users. This session will cover tuning several aspects of your application and the underlying TCP stack to deliver solid performance over the public internet.

The topics of focus will be:

  • The accept loop and the pain of a dropped SYN
  • Tuning TCP Slow Start for short lived connections
  • What you can do at the host level about a DoS
  • TCP offload engines and the unexpected tradeoffs
  • TIME_WAIT and the worst advice ever
  • SSL, keepalive, and cheating the speed of light
