Overview

This document contains the results of testing Sharing local instances(SLI) for MARC Source records. PERF-904 - Getting issue details... STATUS

Summary

• Duration on three tenants cs00000int_0001-cs00000int_0003 for 1 SLI process is about the same and the average value is about 16 seconds.  Duration on the last tenant during test execution cs00000int_0004 is about 6 seconds. For 2 parallel SLIs duration is about 16 seconds on first cs00000int_0001 tenant and 6,5 seconds on second tenant cs00000int_0002. For 3 parallel SLIs and for 4 parallel SLIs is about 16 seconds for all except the last tenant - 6 seconds.
• Duration increased significantly if to compare with approximate 2 seconds in Poppy release.
• After adding parameter Dinventory.sharing.di.status.poll.interval.seconds=2 the duration decreased from 6 seconds to 2,9 seconds for SLI.
• No memory leak is suspected for SLI modules. Memory consumption grew for mod-inventory to 56% during 3-rd test and didn't change.
• Maximum CPU utilization was about 15% on mod-inventory and mod-consortia-b 1VU-23%, 2VU-25%, 3VU-28%, 4VU-35%.
• RDS CPU utilization were from 8% for 1VU and up to 10% for 4VU. That is twice less than in Poppy.
• All SLI finished successfully(without erros). Error rate = 0

Recommendations and Jiras

• It's important to add parameters to task definition to reduce local instance sharing time

  • "name": "JAVA_OPTS",
    "value": " -Dinventory.sharing.di.status.poll.interval.seconds=2"

Test results

Test 1. Virtual user working sequentially on each of the 4 tenants.

Test 2. Virtual users working parallel on 2 tenants.
