The current system can accommodate an average load only without Data Import. With data import, we will have 'HTTP 500 Internal Server Error. If the issue persists, please report it to EBSCO Connect.' for several workflows in the source-storage/records/{id}/formatted requests

, and the general response time will be longer up to 2 times for all other workflows.
Service CPU utilization did not exceed 36% 33% even at the beginning of all processes together. Without spikes at the beginning and start of DI jobs average CPU usage was about 15%. Instance CPU Utilization did not exceed 22%13%.
Service memory utilization was stable, and no memory leaks were suspected during tests.
Each FYR (Fiscal close - end of FY rollover) job is consuming a lot of DB CPU (each spike here corresponds to each FYR job). Approximately DB CPU usage was is up to 95,2% with FYR and up to 92%
Increasing the number of database connections to DB_MAXPOOLSIZE = 200 for mod-source-record-manager and mod-source-record-storage did not give any positive effect on 'HTTP 500 Internal Server Error. If the issue persists, please report it to EBSCO Connect.' but duration of Data Import job was decreased twice.

For Test#1, Test#2 and Test#3 graphs are almost the same. With FYR general throughput is decreased. Possibly, the reason is high database resource usage of FYR.

Memory Utilization

This graph represents memory usage of 3 first test runs and shows that no memory leak is suspected for all of the modules.

Service CPU Utilization

Average CPU usage did not exceed 36 33 % for all modules. We can observe spikes in CPU usage of DI modules at the beginning of the Data Import jobs. Without DI spikes average CPU usage was about 15%.mod-authtoken like in every CICO testing.

Each FYR (Fiscal close - end of FY rollover) job is consuming a lot of DB CPU (each spike here at the start corresponds to each FYR job).

Approximately DB CPU usage is up to 95,2% with FYR and up to 92%75% without.
