### Before Creating the Enhancement Request - [X] I have confirmed that this should be classified as an enhancement rather than a bug/feature. ### Summary 1. a new instance of NettyRemotingClient is created whenever a Consumer started. 2. NettyRemotingClient use NettyClientConfig.clientCallbackExecutorThreads (which is Runtime.getRuntime().availableProcessors() by default) to init the underlying thread pools. 3. if there is 20 consumers/topics and 8 cores, the application will create 160 threads. most of them are in waiting state. this causes performance issues (slow startup) and waste of resources( a lot of waiting threads). ### Motivation predicable resources will make the application stable and resources aware in clould native environment. ### Describe the Solution You'd Like better to share one underlying netty event loop instead creating new one each time. ### Describe Alternatives You've Considered No ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
