Overview

This document contains the results of testing Data Import Create MARC holdings records in Orchid to detect performance trends.

Ticket:

Previous test report: Data Import Create MARC holdings records [Nolana]

Summary

• Data import jobs duration significantly increased compared to the Nolana results, see TestResults. It can be caused by added index on the ncp5 environment on Orchid release to make it production like.
• Maximum CPU utilization was observed for mod-inventory-storage module during 80k DI job - 88%, see ServiceCPUUtilization.
• There is a significant memory utilization increase for some modules during 10k and 80k DI jobs, see MemoryUtilization. 
• Maximum service memory utilization reached 97% for mod-inventory-storage during 80k DI job, see MemoryUtilization.
• During 80k DI job there is a switch of instrances for reader and writer role. This might happen because of overload and restart of the writer instance, see DBCPUUtilization.

DB CPU Utilization

During 80k DI job there is a switch of instrances for reader and writer role. This might happen because of overload and restart of the writer instance.
