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.
Introduction:
Objective:
Results: 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 test. The reduced number of instances in this setup was clearly insufficient to maintain the required performance levels.
