Tomcat native library
When I installed Tomcat 6 + JDK6 on my Linux machine, I get this error when Tomcat is started:May 25, 2007 6:10:26 PM org.apache.catalina.core.AprLifecycleListener init INFO: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/java/jdk1.6.0_01/jre/lib/i386/client:/usr/java/jdk1.6.0_01/jre/lib/i386:/usr/java/jdk1.6.0_01/jre/../lib/i386:/oracle/10g/lib:/lib:/usr/lib:/usr/local/lib:/usr/java/packages/lib/i386:/lib:/usr/lib
Out of curiosity, I go to $TOMCAT_HOME/bin and compiled tomcat_native-1.1.10-src.tar.gz. Before that, I also compiled apr from source.
cd $TOMCAT_HOME/bin tar zxf tomcat_native-1.1.10-src.tar.gz cd tomcat-native-1.1.10-src/jni/native ./configure --with-apr=/usr/local/apr --with-ssl=/usr make && make install
Afterwards, I started Tomcat with java.library.path modified
export JAVA_OPTS="-Djava.library.path=/usr/local/apr/lib" $TOMCAT_HOME/bin/startup.sh
Walla, the error is gone, and is replaced by something that looks appealing. I tried the example pages, didn't notice much of a difference.... But I guess this may have something to do with NIO in Java6.

Once you have tomcat-native library enabled, the default https connector will no longer be serving encrypted contents. Tomcat now uses openssl-style key+certificate. You need to replace the whole connector block with the following:
<Connector port="8443" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" disableUploadTimeout="true" acceptCount="100" scheme="https" secure="true" SSLEngine="on" SSLCertificateFile="/certs/selfsign.crt" SSLCertificateKeyFile="/certs/selfsign.pem" />
