Overview

  • The primary objective of testing was to evaluate the performance of the Baseline MCPT Environment configuration while attempting to optimize costs by adjusting instance types and reducing the number of instances. The tests were designed to compare the performance outcomes across different configurations, including variations in instance types and counts within multiple Auto Scaling Groups (ASGs). By systematically modifying these variables, the goal was to maintain or improve the performance observed in the baseline configuration while achieving cost efficiency.

PERF-962 - Getting issue details... STATUS  

Summary

  • Through a series of experiments involving different placement strategies, instance types, and total instance counts, we found that the performance remained consistent when using these configurations: 
    • three c7g.large instances dedicated to the okapi service alongside five r7g.2xlarge instances for all other services, with the CPU parameter set to 2 for all services.
    • five r7g.2xlarge instances for all services, with the CPU parameter set to 2 for all services.
  • Optimized environment configurations offers a 20-40% cost reduction compared to the existing setup, making it a more economical option without compromising on performance.
  • Configurations with three c7g.large instances for the okapi service and five r7g.2xlarge instances for all other services show the best performance across all experiments.
  • In fact, some workflows show better performance with this new setup than correct infrastructures.
  • The CPU utilization on EC2 level better now - around 30-60%, previously it was under 20%.

Test №3-4

Introduction: Test 3: The Baseline QCP1 Environment configuration was applied, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type:  c7g.large for others services, qcp1_MiniMaster.jmx script was run. Test 3: Repeat Test 1.

Objective: The objective of test was to evaluate the performance of the QCP1 environment by applying two distinct autoscaling groups with different instance types: c7g.large for the Okapi service and r7g.xlarge for all other services. By running test, the goal was to determine if this modified configuration could achieve similar or improved performance compared to the baseline, while potentially optimizing resource allocation and cost. 

Results: We observed nearly identical performance results almost for all the workflows compared to the Baseline configuration and repeated it in Test №4.

Methodology/Approach

Tests scenarios were started by JMeter script from load generator.   

Baseline QCP1 Environment configuration: Parameter srs.marcIndexers.delete.interval.seconds=86400 for mod-source-record-storage,  number of tasks to launch for service mod-marc-migrations-b was set zero. Instance type: m6g.2xlarge. Instances count: 10. Database db.r6g.xlarge, Amazon OpenSearch Service  ptf-test: r6g.2хlarge.search (4 nodes).

  • Test 1: The Baseline QCP1 Environment configuration was applied, qcp1_MiniMaster.jmx script was run.
  • Test 2: The Baseline QCP1 Environment configuration was applied, qcp1_MiniMaster.jmx script was run (Repeat Test 1).
  • Test 3:  The Baseline QCP1 Environment configuration was applied, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type:  c7g.large for others services, qcp1_MiniMaster.jmx script was run.
  • Test 4: The Baseline QCP1 Environment configuration was applied, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type:  c7g.large for others services, qcp1_MiniMaster.jmx script was run (Repeat Test 3).
  • Test 5: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type:  c7g.large for others services, qcp1_MiniMaster.jmx script was run.
  • Test 6: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type:  c7g.large for others services, qcp1_MiniMaster.jmx script was run (Repeat Test 5).
  • Test 7: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules except CPU=2048 for mod-search, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type:  c7g.large for others services, qcp1_MiniMaster.jmx script was run.
  • Test 8: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules, used ONE autoscaling group with 5 Instance Type:  c7g.large for all services, qcp1_MiniMaster.jmx script was run.
  • Test 9: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules, used ONE autoscaling group with 5 Instance Type:  c7g.large for all services, qcp1_MiniMaster.jmx script was run (Repeat Test 8).
  • Test 10: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules except CPU=2048 for mod-search, used ONE autoscaling group with 5 Instance Type:  c7g.large for all services, qcp1_MiniMaster.jmx script was run.
  • Test 11: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules except CPU=2048 for mod-search, used ONE autoscaling group with 5 Instance Type:  c7g.large for all services, qcp1_MiniMaster.jmx script was run (Repeat Test 10).
  • Test 12: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules except CPU=2048 for mod-search, used ONE autoscaling group with 5 Instance Type:  c7g.large for all services, qcp1_MiniMaster.jmx script was run (Repeat Test 11).
