CPU and memory maxing out on performance test

[kplatis]

I did a performance test locally using the following configuration on Postman:

• a container of 1 CPU and 2GB of ram
• 20 virtual users making requests for 2 mins

As it is visible on the following image the CPU of the container maxes out and the memory is not getting released

Also the average response time is ~ 20 seconds which is far from optimal.

I'm looking into this; thanks for the info @kplatis

Running the service locally isn't too bad, from what I can tell. The RSS stays constant at about ~300Mb, the VIRT gets big though, I assume due to fragmentation.

Running 25 clients in parallel, w/ 2 workers and ~100 requests, I get: Response time: 6.12 secs, which isn't great. However, instrumenting the nexus calls, I see (second column is time in seconds):

count  103.000000
mean     4.922631
std      2.271814
min      0.971000
25%      3.534000
50%      4.746000
75%      6.406500
max     10.432000

So that partly explains the above. I'm wondering, however, if the latency is partly a keycloak auth issue. I will continue to investigate.
