Best Practices

  • One of the simplest and most effective ways of improving connection performance is to enable HTTP Persistent Connections, also known as Keep-Alive. This has a profound impact on overall performance by reducing connection management overhead as well as CPU utilization on both sides of the interface.
  • The OpenRTB specifications do not cover security other than recommending plain HTTP for performance reasons.
