Do you know if your problem is latency or throughput? If latency is a problem, switching to the NIO connector may help handle more connections within a given environment. Tomcat 6 claims to have "memory usage optimizations" and "advanced IO capabilities" which would indicate in general that performance is improved. Tomcat 7 has "lots of internal code clean-up" which often, though not always, results in a performance improvement. As always, you should test your actual application to determine any performance boost you would expect to see in a production environment. I think you may be looking at an infrastructure upgrade, though.
