Overview

In this report, PTF investigates the impact of setting CPU allocations to 0 units across all tasks within an AWS ECS cluster. The purpose of this study is to determine whether removing CPU constraints reveals the actual CPU usage of the tasks and to assess how this adjustment affects overall performance. By comparing key workflows across different environments, we aim to identify any potential changes in efficiency, throughput, or resource utilization that may result from setting CPU = 0. The findings from these tests will help inform best practices for resource allocation and performance optimization within ECS clusters.

Summary

Much performance degradation when we use less instance count for environment or instance type: .x2gd.large with less resources.
During the tests Parameter CPU=0 improved performance for a several workflows, so this point we are going to investigate more in this ticket.
No memory leaks, memory consumption was stable during all of the tests.
Tests had 100% errors count for AIE_TC: Create Invoices, AIE_TC: Invoices Approve, AIE_TC: Paying Invoices, TC: Receiving-an-Order-Line, Unreceiving-a-Piece and Unreceiving-a-Piece Workflows because data was not regenerated.

Summary

During the tests Parameter CPU=0 improved performance for a several workflows, like MSF_TC: mod search by auth query, MSF_TC: mod search by contributors, MSF_TC: mod search by title query and ULR_TC: Users loan Renewal Transaction.
No memory leaks, memory consumption was stable during all of the tests.
Tests had 100% errors count for AIE_TC: Create Invoices, AIE_TC: Invoices Approve, AIE_TC: Paying Invoices, TC: Receiving-an-Order-Line, Unreceiving-a-Piece and Unreceiving-a-Piece Workflows because data was not regenerated.

Methodology/Approach

MOBIUS Tests: scenarios were started by JMeter script from load generator. We had 100% error count for AIE_TC: Create Invoices, AIE_TC: Invoices Approve, AIE_TC: Paying Invoices, TC: Receiving-an-Order-Line, Unreceiving-a-Piece and Unreceiving-a-Piece Workflows because data was not regenerated.

Baseline MCPT Environment configuration according to tunning environment from previous report: task count: 4 for services: mod-permissions, mod-search, mod-patron, mod-inventory, mod-inventory-storage, mod-circulation, mod-circulation-storage, mod-order, mod-order-storage, mod-invoice, mod-invoice-storage, for mod-users and mod-authtoken task count 6. Parameter srs.marcIndexers.delete.interval.seconds=86400 for mod-source-record-storage. Instance type: m6g.2xlarge. Instances count: 14. Database r6g.4xlarge, Amazon OpenSearch Service ptf-test: r6g.2хlarge.search (4 nodes).
