JMeter: What could be possible reason of same throughput though user load has increased

What could be the possible reason for throughput remaining the same though load has increased much compared to previous tests? NOTE: I even received the error "Internal Server Error" while running my performance test.

Solution

  • It means you have reached the Saturation Point - the point for maximum performance!

    A certain amount of concurrent users adjoining with maximum CPU utilization and peak throughput. Adding any more concurrent users will lead to degradation of response time and throughput, and will cause peak CPU utilization. Also, it can throw some errors!

    After that, If you continue increasing the number of virtual users you may see these:

    • Response time is increasing.
    • Some of your requests got failed.
    • Throughput is either remains the same or decreases - this indicates the performance bottleneck!
