I see that the performance using MySQL is better than using HSQL. But why does XWiki recommend to use Tomcat as WAS?
I have heard that Jetty is so efficient, lightweight and flexible that it can replace Tomcat in many common cases. So I'm playing with Nginx + configured XEM standalone package (Jetty + MySQL) for prduction. Does XWiki have the other reasons recommending Tomcat? @WhyKesarr. MetaDeveloper.
