The Chrome beta for Android uses an experimental feature to reduce cellular data usage. Tests indicate that this feature has been able to reduce the data usage by 50%. The connections from the mobile device to the proxy now run over SPDY (pronounced speedy), an open networking protocol developed primarily at Google for transporting web content.
The Chrome beta for Android uses an experimental feature to reduce cellular data usage. Tests indicate that this feature has been able to reduce the data usage by 50%. The connections from the mobile device to the proxy now run over SPDY (pronounced speedy), an open networking protocol developed primarily at Google for transporting web content. By using SPDY, the proxy is able to multiplex multiple request and response streams in parallel over a single TCP connection, which has numerous performance benefits: it amortizes TCP handshake overhead for multiple requests, enables higher throughput by removing the TCP slow-start phase incurred by each new connection, and enables intelligent request and response prioritization between the streams.
Further, there are many secondary benefits to using SPDY:

- DNS late-binding: DNS lookups are performed by the proxy, instead of on the phone, which means that the resolutions can be done much, much quicker.
- Less network activity and faster load times also mean that the mobile radio has to be active for shorter periods of time, which translates into longer battery life!
- The SPDY connection runs over SSL, which enables safer and more secure browsing
SPDY helps automation of content optimization which includes transcoding images, content-aware compression, multiplexing and prioritization.
