Edge Security Acceleration:Speed and network overview

Last Updated:Jun 02, 2026

ESA provides speed and network features to monitor, optimize, and extend your website's performance and connectivity. Speed features include performance monitoring, content optimization, and modern protocol support. Network features cover IPv6, WebSocket, gRPC, and upload size controls.

Speed monitoring

Measure your website's real-world performance before applying optimizations.

  • Page monitoring -- Collects real-user performance data on PC and mobile by integrating JavaScript automatically or manually. Tracks metrics in real time, analyzes HTML pages, and grades performance as green, yellow, or red.

  • Adaptive Optimizer -- Injects anonymous JavaScript into specific error and CAPTCHA pages to collect client-side performance data, then transmits the data to data centers for processing and analysis.

Content optimization

Reduce payload sizes and speed up content delivery.

  • Image Transformations -- Transforms the format, quality, and dimensions of images from your origin server. Supports cropping, scaling, and caching to speed up retrieval and reduce origin traffic.

  • Resource compression -- Compresses static resources to reduce transfer sizes and improve page load speed.

Protocol optimization

Enable modern protocols for faster and more efficient connections.

  • HTTP/2 and HTTP/3 (QUIC) -- When you enable SSL/TLS and configure the required certificate for your website, ESA automatically enables HTTP/2 and HTTP/3 (QUIC).

Network optimization

Extend connectivity and support additional access methods.

  • Network optimization -- Optimizes network access and origin fetch with IPv6 support, WebSocket and gRPC connections, and maximum upload size settings.

Plan comparison

Speed and network feature availability by ESA plan.

How to read this table: Numeric values indicate feature-specific limits. "Supported" means the feature is available with no plan-specific limit. "Not supported" means the feature is unavailable on that plan.
