Subject RE: Tomcat benchmarks from orionserver.com, Please comment. Impor tant

I was not implying that load balancing was solely a Tomcat strength.  My
point was that with load-balancing available, performance becomes less of an
issue.  As long as latency is acceptable, throughput can be achieved through
additional hardware.  I find this preferable to trying to performance-tune
software.  Would rather the software code be clean and easy to maintain and
therefore less likely to be buggy.  I will use hardware to increase
performance.  Yes, I was a theoretical computer science major.

Important

I'm not familiar with OrionServer, but Resin is architected to be run
behind
IIS, Apache, etc. It also has a standalone HTTP server ala Tomcat. Load
balancing is not just a Tomcat strength.
