Mao updated KAFKA-8583:
-----------------------
Description:
The is a propose to optimize SslTransportLayer#write(ByteBuffer).
Currently, sslEngine only reads data from src once per selector loop.
This can be optimized by reading all src data in one selector loop.
The propose comes from [Amrby|[https://github.com/linkedin/ambry/pull/1105]],
which uses same Transport Layer code and change has been deployed to prod for 6
months. Unfortunately, Ambry didn't record the perf diff.
Code change: [https://github.com/apache/kafka/pull/6984]
Let me know if anything needed.
