Continuous load and stress testing using k6 to validate speed, stability, and reliability
At OneStopWP, performance isn't a promise — it's continuously measured. This page showcases the results of our ongoing load and performance testing using k6 by Grafana Labs, an industry-standard open-source tool. By simulating real-world WordPress traffic, we verify response times, stability, and reliability under sustained and peak load conditions. These tests help validate OneStopWP's WordPress hosting performance in real-world scenarios.
The resources allocated to your hosting plan — including CPU, memory, and caching — play a critical role in how your site performs under real-world traffic. Our k6 by Grafana Labs load testing highlights how each plan tier handles sustained and peak load scenarios.
Designed for low-traffic sites/blogs and personal projects.
Optimized for growing sites, higher traffic, and demanding workloads.
The data below reflects the aggregated average results across all tested scenarios and hosting plans, simulating a combined load of 1,000 simultaneous virtual users (VUs) to evaluate performance, stability, and response times under sustained traffic.
These scenario-level results highlight how additional CPU, memory, and Redis object caching in the Business plan reduce latency and improve throughput for dynamic WordPress operations under load.
The comparison demonstrates how resource allocation directly affects real-world performance.
| Scenario | Simulated VUs | P95 Latency (ms) | Max Throughput (RPS) | Error Rate | |||
|---|---|---|---|---|---|---|---|
| Personal | Business | Personal | Business | Personal | Business | ||
| Static Homepage Load (Simple GET) | 1,000 | 3.58 | 2.29 | 279 | 818 | 1.19% | 0.55% |
| Dynamic Blog List Page (Low Cache Hit) | 1,000 | 14.32 | 4.12 | 150 | 248 | 0.19% | 0.09% |
| User Login/Auth Cycle (Database Check) | 1,000 | 19.69 | 6.41 | 100 | 359 | 0.10% | 0.05% |
| Complex Checkout Process (Multi-step POST) | 1,000 | 22.75 | 11.45 | 29 | 78 | 0.85% | 0.34% |
These tests are based on 1,000 simultaneous visitors over 10 minutes. Overall requests for the Personal plan: 174,592. Overall requests for the Business plan - 511,294.
Key Takeaway:
The Business Plan demonstrates significantly lower latency (faster response times) for dynamic and database-intensive tasks (Blog List, Login), due to the combined power of 2x Resources and Redis Object Caching. While the Checkout process remains complex and slower on both tiers, the Business Plan handles the load with far fewer errors and lower latency.
