CloudFlare Railgun WAN Optimizer

CloudFlare Railgun WAN Optimizer

By: CloudFlare Inc. Latest Version: 4.0

This version has been removed and is no longer available to new customers.

Product Overview

CloudFlares Railgun uses advanced network optimization to ensure your customers content is delivered as fast as possible. Traditionally, much of the web cannot be cached because it is dynamic. However, even dynamic content changes very slowly. Railgun tracks page changes down to the byte and only sends the bytes that have actually changed across the network. Railgun achieves a 99.6% compression ratio so that what used to take 200 packets now can be sent in a single packet. The result is a 140% additional performance boost for website visitors.

Railgun is available for customers with a CloudFlare Business ($200/month) or Enterprise (starting at $3000/month) plan.
