      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.
