### Motivation Currently `PublishRateLimiterImpl` is used for broker publisher throttling, and checkPublishRate() is called in high frequency (default is 50ms every time). Each time checkPublishRate() is called, `currentPublishByteCount.sum()` and `currentPublishMsgCount.sum()` are executed. `LongAdder.sum()` will sum all cells in the LongAdder object. In case of only byte throttling (or msg count throttling) is enabled, only do the necessary sum operation could improve the performace. ### Modifications In case of only byte throttling (or msg count throttling) is enabled, only do the necessary sum operation. ### Verifying this change Already coverd by PublishRateLimiterTest() ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
