Performance Summary for Document-Literal Web Service with High Payload

  • Payload size: High (200KB)

  • Ramp up: 25 users per minute

  • Iteration pacing: 120 seconds

  • Total test duration: 27 minutes

Figure 4 shows response time versus number of virtual users for this test.

The following table shows the results of each measurement.



Number of users at 29.5% CPU utilization


Total transactions failed


Average response time

0.752 seconds

We see encouraging numbers again. With a heavy payload of 200KB per transaction, we could ramp up the simultaneous users to 500 before hitting 30% CPU utilization. The average roundtrip overhead was noted around 700 milliseconds—still less than a second, under a very heavy load of simultaneous users handling a large payload. Again, the most impressive number was that of no failures in any transactions.
