This feature is not available for Google Chrome Desktop users, however a free Chrome extension now allows users to get the same savings on their desktop computers. The extension sends all HTTP (but not HTTPS) traffic through Chrome Data Compression Proxy server, which utilizes SPDY protocol to speed up web browsing. Users can check bandwidth savings by visiting chrome://net-internals/#bandwidth and can disable compression-proxy by clicking the green bolt icon from the toolbar.
