[jira] [Commented] (KAFKA-2561) Optionally support OpenSSL for
SSL/TLS
[ https://issues.apache.org/jira/browse/KAFKA-2561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15258958#comment-15258958 ]
Scott Kruger commented on KAFKA-2561:
-------------------------------------
Now that Java 9 has been delayed until 2017, can this get a bump in priority?

> JDK's `SSLEngine` is unfortunately a bit slow (KAFKA-2431 covers this in more detail). We should consider supporting OpenSSL for SSL/TLS. Initial experiments on my laptop show that it performs a lot better:

> Extracting the throughput figures:
> * JDK SSLEngine: 94 MB/s
> * OpenSSL SSLEngine: 247 MB/s
> * Plaintext: 337 MB/s (code from trunk, so no zero-copy due to KAFKA-2517)
> In order to get these figures, I used Netty's `OpenSslEngine` by hacking `SSLFactory` to use Netty's `SslContextBuilder` and made a few changes to `SSLTransportLayer` in order to workaround differences in behaviour between `OpenSslEngine` and JDK's SSLEngine (filed https://github.com/netty/netty/issues/4235 and https://github.com/netty/netty/issues/4238 upstream).
