I ran the http-invoker based jpetstore sample. Interestingly, I got reasonably fast response times for up to 3 repetitions of the service request (400 ms or so). Beyond 4 repetitions, though, the performance got worse and worse, and it sort of stabilized at about 2 seconds/request, for, say, a loop of 20 requests.
What is causing this significant performance degradation? The requests are sent sequentially in a loop, so there is always only request dealt with at a time.
Has anyone alse noticed it? Is there a remedy?
