  Users should decide for themselves which Servlet Container they consider the easiest/best for their use cases based on their needs/experience. For high traffic scenarios, investing time for tuning the servlet container can often make a big difference.

+ == How do I change the logging levels/files/format ? ==
+ 
+ Solr uses JDK standard logging, (ie; the java.util.logging.* package), an overview of how that can be configured at the JVM level can be found here...
+ 
+ http://java.sun.com/j2se/1.5.0/docs/guide/logging/overview.html
+ 
+ ...but many servlet containers provide alternate log configuration options in their configuration files.  You should consult your servlet containers documentation to see what options are available.
+ 
+ The Solr Admin console has a [http://localhost:8983/solr/admin/logging.jsp screen for toggling the logging level globally].  This is a transient setting good for doing diagnostic work, but does not persist after reboot.
