PERF-210 - Test Import of MARC Authorities IN REVIEW

UIDATIMP-1033 - Performance Test: Data Import > Create MARC authority records IN PROGRESS


This document contains the results of testing Data Import MARC Authorities in pre-lotus to detect performance trends. 

This document contains result of testing with multiple tenants concurrently with and without Check-in-Check-out process on the background;


  • Differences in times of execution between stand alone job and multitenant 4-5 times (1 min 14 s for 5 k and 5 min 30 s for 5k in multitenant, 2 minutes to 7 minutes in 10k )
  • It’s not so stable when it comes to big files we saw a lot of DB timeouts  (so maybe it will be a good idea to extend timeouts or investigate them deeper)
  • We can see memory usage growing from test to test it might be a sign of memory leak. PERF-223 - Getting issue details... STATUS

Multitenant testing with CICO

  • CICO has no errors during test set
  • Times for DI grew even more +2-3 minutes and +20 minutes for 50K
  • 50K failed (completed with errors) on same tenant as CICO was working on.

Multitenant Marc authority imports 2 tenants

Resources usage

Multitenant Marc authority imports 3 tenants

To test this we've used three tenants with shared resources.

Resources usage

CPU has predicted behavior with one spike at the beginning of the test

As you can see there is growing memory usage from test to test it might be a sign of memory leak. 

COU usage of EC2 instances are less than 30%.
