[ovirt-users] Tunable parameters in ovirt engine

Hi Team, *Description of problem:* I am trying to achieve 1000 concurrent request to oVirt. What are the tunable parameters to achieve this? I tried to perform the benchmarking for ovirt engine using Apache benchmark using the same SSO token. ab -n 1000 -c 500 -k -H "accept: application/json" -H "Authorization: Bearer SSOTOKEN" https://172.30.56.70/ovirt-engine/ <https://172.30.56.70/ovirt-engine/api/vms/5440271b-afb3-48bb-9ff1-076fc07... When the number of concurrent request is 500, we are getting more than 100 failures with the following error, SSL read failed (1) - closing connection 139620982339352:error: NOTE: It is scaling for concurrent request below 500. I used the profiler to get the memory and CPU and it seems very less, PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 30413 ovirt 20 0 4226664 882396 6776 S 126.0 23.0 27:48.53 java Configuration of the machine in which Ovirt is deployed : RAM - 4GB, Hard disk - 100GB, core processor - 2, OS - Cent7.x. In which 2GB is allocated to oVirt. Version-Release number of selected component (if applicable): 4.2.2 How reproducible: If the number of concurrent requests are above 500, we are easily facing this issue. *Actual results:* SSL read failed (1) - closing connection 139620982339352:error: *Expected results:* Request success.
