Hi , Yukon shared us a data flow map with a question. I have tried all my power reading the map without getting a specfic answer. Does anyone have idea with making it a new interesting incubator version! Really appreciate your "bit Data" source for helping on feeding it up! Sorry for any rude actions/impolite words bothered you. Many thanks in advance!

Hi guys, I met a flow control problem. Here is config: Version: rocketmq 3.5.8 Broker: 3m-3s-async flushDiskType:ASYNC_FLUSH Jvm:-Xms 4g -Xmx 4g -xmn 2g -XX:PermSize=128m -XX:MaxPermSize=320m -XX:ParallelGCThreads=2 -XX:ConcGCThreads=1 Env: Docker, no cpu limit, 16G memory,(The host has 40 cpus and deploys about 20-30 docker instances??not mq), all instances is no cpu limit) sendMessageThreadPoolNums=28 pullMessageThreadPoolNums=22 When the tps is only 100-200, some master start flow control.Most of logs in producer is like this: [TIMEOUT_CLEAN_QUEUE]broker busy, start flow control for a while, period in queue: 201ms, size of queue: 35 Some logs is: [REJECTREQUEST]system busy, start flow control for a while [PCBUSY_CLEAN_QUEUE]broker busy, start flow control for a while, period in queue: 3ms, size of queue: 66 There are warning logs in master sometimes, like: [NOTIFYME]putMessage in lock cost time(ms)=1557, bodyLength=108 AppendMessageResult=AppendMessageResult{status=PUT_OK,...pagecacheRT=1557} putMessage not in lock eclipse time(ms)=1557, bodyLength=110 Sometimes pagecacheRT=0. Sometimes only has "not in lock time?? log: putMessage not in lock eclipse time(ms)=1440, bodyLength=108 The flow control happens in one broker mostly??and the others is fine. The gc time is about 100ms??it mostly doesn??t happen is gc period In another cluster, 1m-1s-async with mq config, its tsp can reach 10000 until happening flow control Does anyone have idea about this problem??where is bottleneck probably??memory??disk, or cpu?
