In the previous section ("Java NIO Framework Netty Tutorial (12) Concurrent access Test (middle)"), we tested the Netty concurrency scenarios from all angles. In this section, we will focus on the last issue mentioned in the previous section. In the case of multi-threaded concurrent access, there will beWarning: EXCEPTION, implement One.coder.netty.chapter.eight.ObjectClientHandler.exceptionCaught () for pr

number of threads is 200 and the preparation time is 10, then 1 seconds will be required to start 20 threads. That is, starting 20 threads per second.Loop Count: The number of times each thread sent a request. If the number of threads is 200 and the number of cycles is 10, then each thread sends 10 requests. The total number of requests is 200*10=2000. If "Forever" is checked, all threads will continue to send the request until you choose to stop running the script.Fourth Step: Add summary Repo
