Speed, uptime, and stability are the core of every hosting decision. WP Engine provides a developer-focused infrastructure, but SiteGround continues to dominate real-world performance benchmarks with its cloud-powered architecture.
Independent testing shows SiteGround sites load 30–40% faster on average due to its Google Cloud network and dynamic caching.

Built-in redundancy layers ensure no single point of failure, providing consistent website availability under heavy load.
