wu-sheng commented on issue #3726: Improve visibility for DataCarrier. URL: https://github.com/apache/skywalking/pull/3726#issuecomment-553253716 As @yantaowu told me offline, they are using `Queue#offer` with accepting queue is full and data lost tradeoff. The result is not so different, as we don't make the queue full in our tests. **testBuffer2** is using `#offer` method in the test. ``` Benchmark Mode Cnt Score Error Units ChannelWritePerformanceTest.testBuffer1 thrpt 10 29020.969 ± 613.798 ops/s ChannelWritePerformanceTest.testBuffer2 thrpt 10 32102.383 ± 1715.402 ops/s ```
