Blandt andet vil SPDY gøre det muligt at foretage mange flere forespørgelser over den samme forbindelse, hvilket øger effektiviteten

Det er vel allerede muligt via. http pipelining?

Q: Doesn't HTTP pipelining already solve the latency problem?

A: No. While pipelining does allow for multiple requests to be sent in parallel over a single TCP stream, it is still but a single stream. Any delays in the processing of anything in the stream (either a long request at the head-of-line or packet loss) will delay the entire stream. Pipelining has proven difficult to deploy, and because of this remains disabled by default in all of the major browsers.

Så længe det ikke påvirker webudviklingen.. Altså, skal implementeres på protokol niveau (Selvom artiklen antyder andet), således at det kun er min host der skal gøre noget, og ikke mig..

Goals for SPDY:
[...]
To avoid the need for any changes to content by website authors. The only changes required to support SPDY are in the client user agent and web server applications.

The SPDY project defines and implements an application-layer protocol for the web which greatly reduces latency. The high-level goals for SPDY are:

* To target a 50% reduction in page load time. Our preliminary results have come close to this target (see below).
* To minimize deployment complexity. SPDY uses TCP as the underlying transport layer, so requires no changes to existing networking infrastructure.
* To avoid the need for any changes to content by website authors. The only changes required to support SPDY are in the client user agent and web server applications.
* To bring together like-minded parties interested in exploring protocols as a way of solving the latency problem. We hope to develop this new protocol in partnership with the open-source community and industry specialists.


Some specific technical goals are:

*

To allow many concurrent HTTP requests to run across a single TCP session.
*

To reduce the bandwidth currently used by HTTP by compressing headers and eliminating unnecessary headers.
*

To define a protocol that is easy to implement and server-efficient. We hope to reduce the complexity of HTTP by cutting down on edge cases and defining easily parsed message formats.
* To make SSL the underlying transport protocol, for better security and compatibility with existing network infrastructure. Although SSL does introduce a latency penalty, we believe that the long-term future of the web depends on a secure network connection. In addition, the use of SSL is necessary to ensure that communication across existing proxies is not broken.
* To enable the server to initiate communications with the client and push data to the client whenever possible.

vil frigive en SPDY-kompatibel webserver som open source i den kommende uge.

Hvis de nu frigav en apache patch, ville det hurtigt spredes til hovedparten af sider. Hvad skal vi med en ny webserver?

Woohooo! Nu kan jeg komme 50% hurtigere. til p0rn-siderne..
