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 

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

Software versions

  • mod-data-import:2.5.0

Resources usage

Here CPU usage is not higher than 60% for all related modules.

Concerning behavior on :

  • mod-source-record-manager growing memory from 55% up to 93%
  • mod-source-record-storage growing memory from 41% up to 64%

However last test for 80K didn't showed any memory growing for any of module, so maybe growing of mem usage can be explained as working condition of this modules. 



RDS CPU usage reached 80% maximum during test.
