[GitHub] [rocketmq] socutes opened a new issue, #6105: Optimize the timer implementation in Remoting
socutes opened a new issue, #6105:
URL: https://github.com/apache/rocketmq/issues/6105
Timer is a common and effective tool for timing tasks. java provides several Timer tools, such as java.util.Timer and ScheduledThreadPoolExecutor.but these tools are flawed in execution efficiency.
In the scenario of high concurrency and high traffic flow processing. some subtle performance differences, often have the effect of amplification, resulting in serious performance degradation.
Therefore, you are advised to replace scheduled task scheduling [java.util.Timer](https://github.com/apache/rocketmq/issues/java.util.Timer) with [io.netty.util.HashedWheelTimer](https://github.com/apache/rocketmq/issues/io.netty.util.HashedWheelTimer) in Remoting.
