Overview

This document contains the results of testing Sharing local instances(SLI) for MARC Source records.

Summary

• Duration on all of the tenants cs00000int_0001-cs00000int_0004 for 1 SLI process is about the same and the average value is about 2 seconds.  For 2 parallel SLIs duration is about 2.2 Seconds, for 3 parallel SLIs 2.15 seconds and for 4 parallel SLIs is 2.1.
• No memory leak is suspected for SLI modules. Memory consumption was quite low in comparison to the "before-test" state.
• Maximal CPU utilization was about 17% on mod-inventory and mod-quick-marc. 
• RDS CPU utilization were from 15% for 1VU and up to 20% for 4VU;

...

Test parameters inventory.sharing.di.status.poll.interval.seconds= 1 and inventory.sharing.di.status.poll.number = 5(default)
Test 1. 1 Virtual user working consistently sequentially on each of the 4 tenants.

...

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

...

Resource Utilization Test 1,2,3,4. 

Below are the resource utilization graphs for all tests.

Memory Utilization

Memory usage was stable over 4 tests no memory leak is suspected for all modules, on the graph there are 10 most memory-consuming services.
