Google aims for faster Web downloads with SPDY protocol

But Google will need Microsoft's support for the protocol to become a success, a web developer says

Google is hoping to make Web pages download up to twice as quickly using SPDY, a new application-layer protocol it's experimenting with, the company said in a blog post.

It wants to improve on the performance of using HTTP (Hypertext Transfer Protocol) by minimizing latency. For the protocol to work, the browser and the web server have to be upgraded, but changes to Web pages are not needed, according to Google.

Google's lab tests of SPDY show an improvement in page load times compared to HTTP of between 27 percent and 60 percent, and between 39 percent and 55 percent when using SSL (Secure Sockets Layer), it said.

The company still needs to do a lot of work to evaluate the performance of SPDY in real-world conditions, the blog post said.

Google conducted the tests by downloading 25 of the "top 100" web sites ten times each over simulated home network connections, using a prototype Google Chrome browser and a Web server that it has developed.

SPDY uses a number of techniques to speed Web downloads, including allowing many concurrent HTTP requests across a single TCP session, prioritizing the requests, and using compression to reduce the number of packets and overall amount of data sent.

Google doesn't want to start from scratch with SPDY. The protocol still uses HTTP headers, but it overrides other parts of the protocol, such as connection management and data transfer formats.

"That Google is trying to improve download speeds is great, and the numbers are very promising," said Mans Jonasson, a web developer at IIS, which is responsible for the top-level Swedish Internet domain, .se.

For something like SPDY to work everyone has to be on board. The protocol won't become a success unless it's supported in both Internet Explorer and Firefox, according to Jonasson.

It might be able to convince Mozilla to implement the protocol in Firefox, but convincing Microsoft will be difficult, he said.

"Microsoft seems to hate everything Google does," said Jonasson.

The source code for the prototype Google Chrome browser is available for download. The code for the server will be released as open source in the near future, it said.

That Google is opening up the code is good, but it also needs to approach standards organization IETF (Internet Engineering Task Force), Jonasson said.

Development efforts on other protocols to speed Web downloads, such as SCTP (Stream Control Transmission Protocol) and SST (Structured Stream Transport), have seen little activity in recent years.

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
