Chat

• Chatrooms with users exchanging messages

  • using TCP sockets
  • based on Volano Java benchmark

• Large number of threads and blocking reads

  • 1 room = 20 users = 80 threads
  • 100 messages per user = 38,000 msgs per room

• (20,100) = 20 rooms with 100 msgs/user

• Microbenchmark isolates problem & solutions
