Test №3
Introduction: The Baseline MCPT Environment configuration was applied, the instance type was changed to x2gd.xlarge, the number of instances was changed to 6, and CPU=0 was set for all services.
Objective: The objective of this test is to assess the impact of using fewer, more memory-optimized instances (from m6g.2xlarge to x2gd.xlarge) on the performance of the MCPT environment. By reducing the number of instances while selecting a different instance type with a higher memory-to-vCPU ratio, this test aims to observe how the system handles workloads under these conditions and whether the overall efficiency and performance improve.
Results: This configuration led to a significant performance degradation, with performance being four times worse compared to the baseline testBaseline Test №1. The reduced number of instances in this setup was clearly insufficient to maintain the required performance levels.

Test №4
Introduction: The Baseline MCPT Environment configuration was applied, the instance type was changed to x2gd.xlarge, the number of instances was changed to 8, and CPU=0 was set for all services.Introduction:
Objective: Results: The goal of this test is to evaluate whether increasing the number of instances from 6 to 8, while maintaining the instance type as x2gd.xlarge and setting CPU=0 for all services, can mitigate the performance degradation observed in Test №3. This test aims to determine the optimal instance count needed to maintain stable performance in the MCPT environment under these conditions
Results: As a result, there was a 3x improvement in overall average duration for all workflows compared to Test №3. However, performance still lagged by more than 30% when compared to the Baseline Test №1.
