One of my current projects involves me performance testing a third party Java system. In essence, it's a distributed/n-tier Java EE web application and we're hitting it with a high simulated load thanks to Apache JMeter. One of the things we found is that performance degraded quite dramatically as load increased, to the point where some requests could take anywhere up to a minute or two to be serviced. By plotting the raw results and calculating (for example) the 95% percentile, we were able to see that only a very small number of the requests suffered in this way.
