Very interesting.
So if you have a typical large-app production environment with a
hardware ssl (for example by the load balancer) you don't need the
APR?
you'd need APR or NIO to be able to sustain a large number of keep
alives. If you don't use keep alives, then it wont matter
Tomcat Native -> APR lib -> C is no difference than NIO -> VM -> C,
hence the performance shouldn't be very different.

Hence another evidence that java's performance are equal or better
than c?

thats correct, it will be included in 6.0, in terms of performance it
ranks like this
HTTP Nr Of Connections < maxThreads
1. Blocking IO Connector
2. Java NIO connector and APR connector are fairly similar
HTTP Nr Of Connections > maxThreads
1. Java NIO connector and APR connector are fairly similar
2. Blocking IO Connector
HTTPS
1. The APR connector due to built in with native OpenSSL
2. NIO connector
3. Blocking IO connector
