G'day Also worth considering whether the JMeter JVM has enough memory. If it doesn't the JVM will spend a lot of time garbage collection. The JVM does not useful work while garbage collecting but the real time ticks away and this will give you longer response times.
Easiest way to see if this is significant is to use the JMeter parameters to give JMeter a lot more memory and then see if it makes any difference to the average response time.

But I doubt this makes much difference. The TCs also include downloads of stylesheets, which are the same in both cases. JMeter does not currently cache such repeated downloads (this is planned as a future enhancement), but perhaps the other test tools do. Likewise for the common javascript (only appears once in the plan, but would beome important for loops). What happens if you compare the raw figures for the individual pages in the test plan?
