   > > @baihezhuo 可以试下，这个[PR](https://github.com/apache/rocketmq/pull/1516)对同步双写的性能做了较为明显的提升，你可以验证一下，欢迎给出反馈。

   > 其实我并不是为了提升性能，根本问题是因为通过console发现producer的tps并不高，200左右的时候就会出现大量的流控，而且也不仅仅是高峰期，平时也都会有一些流控的消息；通过线上日志发现很多的：
   > WARN SendMessageThread_46 - putMessage not in lock eclipse time(ms)=3382, bodyLength=78
   > 我临时也在看HA的相关代码，期望能从中找出解决这个问题的思路
   
   差不多的情况 ,  线上环境  TPS 200左右就出现被流控, 这个很不舒服,我感觉是不是RocketMq的流控太过敏感了,或者流控机制有待优化.
   我这边的参数和你的差不多  brokerRole = ASYNC_MASTER
