The Need for Speed

To see Google engineers talk about this, check out the 3 1/2 minute video on this page. You can also check out the video on this page which includes the statement that 100 milliseconds is a recognized threshold for users to notice some sluggishness. You can also see more on Googles thoughts on performance in this Jake Brutlag post titled: Speed Matters. The testing discussed in this post showed that small increases in load time of search results pages, less than 1/2 second, resulted in a decline in searches performed of 0.2% to 0.6%.

Google seems fully prepared to take on the task of rebuilding the Internet if need be, and they are challenging some of the most basic protocols on which the web was built. They have an initiative in place to re-design the HTTP: protocol. Their proposed protocol, known as SPDY: is designed for todays web environment, which HTTP was not. Testing they have done on SPDY shows a 50% uplift in performance " not bad.

Google has also launched its own Public DNS. The DNS infrastructure plays a critical role in the web, that of converting human friendly web addresses, such as www.stonetemple.com, to machine friendly IP addresses, such as 206.130.117.215. Todays web pages often involve multiple DNS lookups to load. Speeding up these transactions can only improve overall performance

The we have Chrome. CNet published a study comparing the Javascript performance of Chrome against two versions of IE, Firefox and Safari. Chrome offered 5x to 10x the performance in running the Javascript tests. Similar data was shown in tests performed by codemeit.

Google is providing some interesting tools for publishers as well. In December 2009 they announced Speed Tracer, a tool for monitoring page load time performance. One key component of the tool is that it allows you to graphically locate trouble spots and then drill down to see what the source of the problem is. In addition, Google Webmaster Tools allows you to get a close up look at your sites performance:

The tool will also let you drill down and get specific suggestions from Google on how to improve site performance:

Last, but not least, at Pubcon 2009 in Las Vegas, Matt Cutts stated quite clearly that Site Speed would become a ranking factor. Of course, that does not necessarily mean it actually will be done, but when you look at the overall commitment that Google has to web performance, you can count on it. So when should you begin working on your site performance? Id say now. Turn site speed into advantage for your business!
