Selecting a web host requires examining actual performance data. This analysis examines five hosting providers based on independent testing from August 2025. The data comes from GTmetrix, Hostingstep, Pingdom, SpeedVitals, and other monitoring services.
GreenGeeks Leads in Speed and Environmental Transparency
GreenGeeks achieves a Time to First Byte of 253 milliseconds according to GTmetrix standard testing. Hostingstep reports a real-world median of 395 milliseconds. North American response times range from 26 to 55 milliseconds based on SpeedVitals 2025 data. International tests show 1.2 to 2.0 seconds for India connections.
The Largest Contentful Paint metric reaches 485 milliseconds in GTmetrix tests from 2025. Sites with managed caching enabled load in under 1.5 seconds according to Pingdom's May 2025 measurements.
GreenGeeks promises 99.9% uptime through its service level agreement. Third-party monitoring from Hostingstep and Pingdom shows actual uptime between 99.96% and 99.98% year-to-date. No major downtimes occurred in 2025 so far.
Load testing through Loader.io demonstrates stability. The servers maintain 26-millisecond average response with zero errors for up to 50 users. Performance remains stable until resource saturation occurs at 1,000 or more simultaneous users. This matches expectations for shared hosting environments.
WordPress benchmark tests using the WPBenchmark plugin show superior CPU and storage speeds. The platform uses NVMe SSD technology and LiteSpeed server stack with LSCache enabled by default.
