Can you run a load test from another computer on the local network? Something like apache AB gives a histogram and you should be able to tell what percentage of your requests is the 5 seconds range. It is best to run it directly to the tomcat private IP that is used inside the local network, to make the path from the load test client to tomcat as short as possible. That depends on your network configuration, which varies among different colos and clouds.
If the loaded tomcat does not max the system resources (which can happen if the application depends on an external app, like a relational database or web service) you can even run AB on the same machine and get close enough results, with the benefit of eliminating potential network delays that may be a suspect. Before you run the load test, do a wget or something like that from the client machine to ensure that you are getting the correct response. AB will also give you the size of the response, which you can use to verify that the client actually gets correct responses from tomcat. If you have something fronting tomcat, you can run the load test once to tomcat and again to the fronting application or load balancer. You will get a general idea of latency of the different components.
