Edge Security Acceleration (ESA) offers two major ways to improve website performance: speed optimization and network optimization.
Features overview
Speed optimization focuses on image transformations, resource compression, and protocol optimization. Network optimization supports IPv6, WebSocket, gRPC, and the configuration of the maximum upload size to enhance website performance in various scenarios.
Speed optimization
In various business contexts, you may need to resize, crop, rotate, or compress images from content sharing websites. However, initiating an origin request for each image processing task can substantially increase the number of origin requests and the cache size on points of presence (POPs). To address these challenges, ESA provides the image transformations feature. You can directly convert images based on your business requirements on ESA POPs.
ESA provides the Gzip, Brotli, and Zstd compression methods to accelerate page loading. Different algorithms are used to compress data, reducing the size of data transferred, shortening the loading time, and saving bandwidth.
Configure protocol optimization
HTTP/2 and HTTP/3 (QUIC) are Internet protocols designed to improve network application performance, optimize web-page-based transmission efficiency, reduce latency, and improve overall performance. If you enable the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) feature and correctly configure the required certificate for your website, ESA automatically turns on the HTTP/2 and HTTP/3 (QUIC) switches to allow you to use the HTTP/2 and HTTP/3 protocols.
Network optimization
ESA provides the network optimization feature, which supports IPv6, WebSocket, and gRPC. WebSocket implements low-latency real-time communication, and gRPC improves inter-service communication efficiency. You can also specify a maximum upload size based on your business requirements to ensure the system security and stability. These policies work together to provide faster, safer, and more stable network services.
