[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=16248386#comment-16248386 ]
jaikiran pai commented on KAFKA-2561:
-------------------------------------
> Later this week, I plan to rerun the same thing with Java 9 and see how it performs.
The same blog[1] has now been updated to include the performance numbers when Java 9 was used. To summarize, there's a drastic improvement in the SSLEngine shipped in JRE 9 as compared to JRE 8. OpenSSL (backed by WildFly OpenSSL), however, still out-performs the default shipped SSLEngine even in Java 9.

> 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).
