Should You Abandon Threads?

• No: important for high-end servers (e.g. databases).

• But, avoid threads wherever possible:

  • Use events, not threads, for GUIs,distributed systems, low-end servers.
  • Only use threads where true CPUconcurrency is needed.
  • Where threads needed, isolate usagein threaded application kernel: keepmost of code single-threaded.
