Overview

This document contains the results of testing List App refreshing of 200k records in the Orchid release. PERF-619 - Getting issue details... STATUS

Summary

Duration for list refresh of 200k records is up to 11 minutes 40 seconds for 10 concurrent users.
Memory utilization increasing for mod-lists up to 33% due to previous module restarting and everyday cluster shutdown processes - no memory leak is suspected for all of the modules.
For mod-lists, CPU utilization was up to 384% for the test with 10 concurrent users and R/W split disabled. Average CPU usage did not exceed 13 % for all other modules.
Approximately DB CPU usage is up to 99.5%.

Recommendations and Jiras

Use database read-write split enabled for mod-lists to improve performance.
Increase default CPU allocation for mod-list service up to 4x to 512 from 128.

Service CPU Utilization

For mod-lists, CPU utilization was up to 384% for the test with 10 concurrent users and R/W split disabled. Average CPU usage did not exceed 13 % for all other modules. Each CPU spike corresponds to a separate list refresh.

RDS CPU Utilization

RDS CPU Utilization was very high. Approximately DB CPU usage is up to 99.5%

RDS Database Connections

DB Load

Long-running queries:

select id from [tenant]_mod_fqm_manager.drv_item_details where lower(cast(item_status as varchar)) = lower($1) order by item_effective_call_number asc, item_effective_location_name asc, instance_title asc, instance_primary_contributor asc

delete from list_contents where list_id=$1 and refresh_id=$2

Methodology/Approach

To test Baseline for List refresh JMeter scripts were used.

Test preparation:

Background circulation jobs were disabled.
200k items were checked out
10 lists were created with the query: (item_status == "Checked out") to be able to run a test for 10 concurrent users.

Refresh list for 1, 2, 5, and 10 concurrent users tested
