------------------------------------
Hello：
For records that do not require compression, I tried using
ByteBufferOutputStream instead of DataOutputStream, but the test results showed
that the performance did not change significantly.
MyTestCode:[^MyProducerTest.java]
ByteBufferOutputStream Test result : [^ByteBufferOutpuStream-Testresult.txt]
DataOutputStream Test result：[^DataOutputStream-TestResult.txt]
Code modification record：[https://github.com/apache/kafka/pull/16595]
Can anyone give me some advice?
Thank you
