Virtual hosts and webapps are both looked up via Hashtables (Tomcat 3.x)
or HashMaps (Tomcat 4.x), so the cost is indeed very small - so small that
it's basically not worth worrying about for a standalone Tomcat
installation.
When you're using Tomcat behind a web connector, it really depends on how
the connector is implemented -- and someone else will have to answer those
questions; I never use 'em so don't have any idea.
