It's been found after testing that the actual durations of the imports performed were about 2 (two) times longer than what was reported. This is due to the PTF environment missing a DB trigger that, when restored, doubled the imports' durations.

Overview

The target of the test is to investigate the impact of Check-In/Check-Out activities during Data Import - MARC Holdings operations and to compare tested results with direct non-intersecting activities' baselines.

PERF-291 - Getting issue details... STATUS

Summary

  • Test results don't show a huge negative impact of Check-In/Check-Out activities during Data Import - MARC Holdings operations:
    • Response time of CI/CO activities during Data Import - MARC Holdings was increased (degradation) by more than 25%.
    • Duration of Data Import - MARC Holdings with CI/CO activities was decreased by 66%. 
  • High Memory usage was detected for mod-inventory-storage (memory usage is 106%, it's >100%) but stable during the test 
  • Memory usage of mod-source-record-storage was increased from 55% to 58%
  • All modules show expected CPU behaviour and typical workload, except 'mod-source-record-manager' and 'mod-authtoken'
  • During the test, there were detected several requests with more than a 1-second response time. (see Additional Screenshots of graphs or charts)

Recommendations & Jiras

  • During future tests, pay attention to:
    • Memory usage of mod-inventory-storage, mod-source-record-storage
    • CPU usage of mod-source-record-manager, mod-authtoken
  • To discuss Data Import - MARC Holdings' behaviour during Check-In/Check-Out activities Martin Tran Artem Vronik Roman_Fedynyshyn

Methodology/Approach

  1. DB Refresh
  2. Run a CI/CO circulation test by Jenkins job
  3. Data Import MARC Holding job running with 5 minutes interval
