Curious if there have been any scalability and performance benchmarks run on Virgo 3 with Tomcat. Curious how I would go about configuring it for HA.

We were planning for our web app to run with Apache fronting n-number of Tomcat instances with mod_jk. If we migrated to Virgo, what would be our path here?

I haven't seen any such benchmarks, but from the experience of running DM server in production (currently migrating to Virgo), I'd say performance-wise there is no significant (if any) difference to plain Tomcat.

As far as scalability is concerned, do the same as you would with plain Tomcat - configure mod_jk (proxy_ajp) for sticky sessions so that load balancing is at its most efficient (i.e. a single session conversation always handled by the same background node), and for failover configure Tomcat session replication and mark your web applications as distributed.
