Overview

The purpose of this document is to analyse, store and summarise load model for National Library of Australia.

Approaches

For NLA load model we did use two different approaches to create load model:

According to data provided in NLA workflow document we can see that rates of TPM (transaction per minute) is low. So we decided to go with 1 request per minute for all sub-workflows (for example create patron, delete patron, create item). This load model will be used as a realistic load;
Second approach is based on relativity between calls. As a assumption we took that workflows that has low rate we'll simulate as 1 transaction per minute. From this assumption we did extrapolate numbers for another sub-workflows.

All numbers and calculations will be provided below.

*here we have two load models, column Realistic and Stress. Users (VUsers) will be used in load model (and JMeter script) as a generators for TPS.

Data import profiles:

DISC HRID match - for importing updated records from DLC on a nightly basis
DISC New edeposit records - for importing new edeposit records from DLC on a nightly basis.
DISC New NON edeposit records - for importing new records, that are not edeposit, on a nightly basis
DS LA edeposit records update - for importing the weekly file of updated records from Libraries Australia
DS HRID match instance overlay - for importing files of bib records that have been previously exported and edited
