Tool used - HP LoadRunner 12.5; Protocol used - Ajax TruClient. The application is hosted on Nederland location.
we are performing load tests with the same number of scripts simulating the load from Nederlands (40 vusers), China (20 vusers) and USA locations (40 vusers). Given the response time of these tests return similar results, we have noticed a very drastic difference in the Throughput. The Nederlands location has returned very less throughput and the other two locations, even though there is a difference in load returned similar throughput. The difference is by a margin of over 150%.
The test duration was 1 hour for each of the test which were executed one after the other (Nederland -> USA -> China). Client side caching was disabled and there is no caching activity was turned on in the servers or the Load Balancer as well.
Please help us by giving a perspective to look at in resolving this mystery.
