APR is essential if Java doesn't support the encryption algorithm of the
SSL / TLS certificate provided by your Certificate authority. It allows
Tomcat to be trusted by your OS to use the system libraries (e.g.
OpenSSL). The system libraries can also be faster under certain
conditions. Only applies if you need a
Connector->SSLHostConfig->Certificate in server.xml.

Hello Romain,
Just to be sure. Your answer is: for production deployment, it is strongly
advised to install APR even if, regarding performance topic, the difference
between APR/HTTP is no more so significant.
It i no more a high recommandation
So curiosity question: if APR doesn't bring so much performance increase, what
is the real added value of using APR ? stability ? other ?
If the load balancing etc is well configured nothing I can think about anymore.
Best Regards.

Hi François,
yes it is the case. Now on a pure performance point of view APR/HTTP is no more
as significant as it was years ago.

Hello everyone,
In the TomEE statup log, I can see this message :
27-Oct-2017 14:58:44.592 INFO [main]
sun.reflect.DelegatingMethodAccessorImpl.invoke The APR based Apache Tomcat
Native library which allows optimal performance in production environments was
not found on the java.library.path: ....
So my question is basic: do we need to install APR for production environment
to improve significantly the TomEE/ Tomcat performance knowing that we don't
integrate TomEE with native server technology like Apache server (eg TomEE
standalone)?
My first APR understanding is that it is useful when you integrate Tomcat in
Apache server (meaning we don't need to install it if we use Tomcat/TomEE
standalone). Am I right ?
Best Regards.
