What does these numbers really tell me and how to retest? Declining throughput in performance test under...

I have a case system where there are 230 people using it to handle claims. There has been a problem for a while that users claims the system works veeery slow in PROD. Our vendor dosen't understand it, and dosen't know how to performance test so I had to do it.I have been using Neoload on 3 computers for the test, and disabled any other software that could have disrupted the test.



The numbers I found using 150 users at the same time with randomized +35% think time, different cases in the request (random, so never the same(?)) and 70 users at the same setup as described with 150 users was:



Average Page response time: 4.3 s(70 users) to 12.3 s(150 users)
Average Request response time: 0.779 s (70 users) to 1.99 s(150 users)
Average throughput: 2,83mb/s(70 users) til 2,00mb/s (150 users)



To me this seems like the application under test dosen't scale well?
Pages that seems to fetch information in tables are the onces who uses the most time. I don't have access to the source code, and can only observe what the loadtest tells me.



I have added these graphs in case it makes it easier (Please disregard the 35 as it was 35 users running per machine x 2 = 70 users at once)



AVERAGE_PAGE_RESPONSE



AVERAGE_REQUEST_RESPONSE



REQUESTS_PER_SECOND
