I believe Jean-Frederic Clere (works with Rémy) has been using 10G interfaces for the Tomcat performance testing, including using APR. I don't have his slides handy... perhaps they show an unexplained performance drop when using APR/tcnative? Or perhaps they show no performance drop (relative to httpd). That would be interesting to see. -chris
