Overview

Tests were conducted in scope of PERF-597 task to assess performance of the Collection Service functionality (RIH scenario in JMeter script) and get the baseline numbers for future testing.

Summary

There is no difference in performance of functionality between normal and high load tests.
There is response time degradation in comparison with tests for all the workflows running at the same time. Details can be found at the Test results part.
During load test CPU utilization for nginx-okapi, mod-inventory-storage, pub-okapi, okapi-b and mod-source-record-storage modules increased to max 5%. Rest of the modules CPU utilization didn't change.
Service memory utilization was stable, and no memory leaks were suspected during tests.

Test Runs

Test #	Test type	# configuration	Test duration	Comment
1	Normal load	RIH scenario with load of 3 requests/second	1 hour	Tests were conducted 2 times each, no differences in results were observed
2	High load	RIH scenario with load of 20 requests/second	1 hour

Instance CPU Utilization

normal load

Instance CPU Utilization did not exceed 7,5%.

high load

Instance CPU Utilization did not exceed 8,5%, except 1 spike at the beginning of the test.

Service CPU Utilization

normal load

During load test CPU utilization for nginx-okapi, mod-inventory-storage, pub-okapi and okapi-b modules increased to 1-1,5%. Rest of the modules CPU didn't change.

high load

During load test CPU utilization for nginx-okapi, mod-inventory-storage, pub-okapi and okapi-b modules increased to 5%, CPU utilization for mod-source-record-storage increased to 2%. Rest of the modules CPU didn't change.

Service Memory Utilization

normal load

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

high load

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

DB CPU Utilization

normal load

DB CPU usage was at the same level as without load - about 7,5%.

high load

DB CPU usage increased from 7,2% to 8,5%.

DB Connections

normal load

Connections count didn't change during the test.

high load

Connections count didn't change during the test.
