Web Service Performance Tips

Posted on July 29, 2008 by Jianming Li
  • Prefer coarse grained operations
  • Prefer asynchronous messaging
  • Use caching when feasible
    • Cache data on client side whenever possible while still ensuring up-to-dateness with server
    • Cache WSDL
    • Cache schemas
    • Cache session state for transactional ws
  • Disable non essential XML parser functionalities (e.g. wellformness) in production
  • Use simple SOAP types (type conversions are costly)
  • Use load balancing (hardware or software)
  • Free resources when finished
  • Determine bottlenecks before fixing any particular part
    • Collect performance metrics periodically
    • Use stress test tools (e.g. PushToTest, Test Director)
