the speed of the connectors are (in order)
Http11Protocol - Java BIO connector, no poller, blocking read/write
Http11AprProtocol - APR connector, poller, blocking read/write
Http11NioProtocol - Java NIO connector, poller, simulated blocking
read/write
the reason the NIO is slower, is cause it has to simulate "blocking"
reads and writes through a non blocking API.The reason the BIO is the
fastest, is cause there is no context switching during block simulation,
or adding/removing the connection from a poller.
When it comes to SSL, the APR connector is much faster than both the
Java connectors.

Has anyone got a comparison of the NIO one vs standard java connectors ?
both with and without the native libs ?

Yep just found the other option, and a site that got me up to speed very
quickly. I can now communicate between Apache and Tomcat.

I'd also recommend that you compile the apr native libs for tomcat
(apache-tomcat-6.0.14/bin/tomcat-native.tar.gz) and enable it when you start
tomcat by adding "-Djava.library.path=/usr/local/apr/lib" (I installed the lib
in /usr/local/apr/lib).
What gives you is the apr interface for handling the http connects.
from the catalina.out:
Nov 26, 2007 9:31:10 AM org.apache.coyote.http11.Http11AprProtocol init
INFO: Initializing Coyote HTTP/1.1 on http-8080
This handler scales and is quicker than the java handler. JBoss calls it
JBossWeb. See http://labs.jboss.com/jbossweb/index.html for a nice graph of the
performance differences between the native apr & java handlers.
