> When the Netty conf org.apache.ratis.thirdparty.io.netty.allocator.useCacheForAllThreads is set to true, it may cause Netty to create a lot garbage objects and, as a result, trigger GC.  We found this problem in RATIS-534.
> Unfortunately, the Netty default is true.  In this JIRA, we will set it the false in GrpcFactory when the conf is not set.
