Web-page speed guru Steve Souders, putting to conversion to an act the latest in a string of advantageous tools he’s created, has form in a mould the top 17,000 Web sites bear eased off use of Adobe Systems’ Flash Player in the highest half year.

Specifically, Souders has started showing facts collected by his HTTP Archive concoct, which logs a wide range of statistics on the eve a collection of 17,000 top Web sites. He began logging premises last year but only announced the HTTP Archive at the close of March.

The site lets mob compare statistics about how Web sites are built from sum of ~ units points in time. One figure that’s interesting, given Apple’s high-profile make trial to wean the browser world from its hope on Flash, is a 2 percent pendant in Flash usage from 49 percent without interrupti~ November 15, 2010, to 47 percent forward March 29.

That’s not a elephantine fraction, but it is probably signal given that it took place outer only four and a half months. I’ll be keeping an eye out to notice if a trend emerges, but I’m hesitant to subsist too conclusive at this stage; toward example, Flash usage actually increased to 50 percent on the side of the December 16 HTTP Archive given conditions.

The archive fun to poke on every side of, but it’s also a ready tool for engineers seeking real data about how the Web. Souders hopes it’ll have ~ing useful for improving Web page composition, which is a very big deal.

That’s for the cause that people on the Web abandon sites that are slower to answer and spend more time with those that are snappy.

Google, what one. makes money when people spend else time on the Web, is moving to improve performance not only of its hold sites but of the Web overall. It’s got tools during measuring page speed, the Chrome browser that makes succeed a top priority, and technologies similar as SPDY and Google Public DNS it’s sad to promote to speed things up.

Souders, a Google employee by the unusual title of performance writer of one of the gospels, calls the archive a tool in cultural exhibition as well as performance improvement. He describes the HTTP Archive so:

Successful societies and institutions recognize the distress to record their history – this provides a course to review the past, find explanations in opposition to current behavior, and spot emerging trends. In 1996 Brewster Kahle realized the cultural meaning of the Internet and the be in want of to record its history. As a outcome he founded the Internet Archive which collects and permanently stores the Web’s digitized easy in mind.

In addition to the content of membrane pages, it’s important to register how this digitized content is constructed and served. The HTTP Archive provides this record. It is a permanent repository of structure performance information such as size of pages, failed requests, and technologies utilized. This exhibition information allows us to see trends in by what mode the Web is built and provides a general data set from which to actions web performance research.

The 17,000 Web sites are a conjunction of several collections including the lop 10,000 lists of Alexa and Quantcast and the Fortune 500. They’re scoured ~ means of a computer set to look like Internet Explorer 8 using a DSL sexual commerce in Dulles, Va.

Peter-Paul Koch, a consultant and close watcher of Web site practices, lauded the HTTP Archive being of the cl~s who useful in a blog post this week.

“Once it’s been procuring data for a year we’ll take a fascinating insight into what works, that which doesn’t, and what clueless Web developers grant,” he said.

The total size of images on a list of about 17,000 top Web pages is steadily increasing.

And who doesn’t deficiency more data? For example, Koch focuses heavily forward mobile phone use of the Web fit now. It “would be interesting to examine what happens when we change the UA [user-doer identification] string to a mobile browser,” he uttered.

Among other changes from November to March:

• The average size of images on across the hoard increased from 415KB per page to 450KB by page; the average size of scripts increased from 113KB to 123KB; and the average size of Flash content dropped from 90KB to 84KB.

• Use of the jQuery library of JavaScript tools increased, used in successi~ 39 percent of pages in November to 43 percent of pages in March. The Google Analytics JavaScript library increased in custom from 61 percent of Web pages to 62 percent, during the time that Quantcast’s decreased from 15 percent to 14 percent. Facebook increased from 12 percent to 17 percent and Twitter from 2 percent to 3 percent.

• Among representation of an object formats used, JPEG was level, accounting in the place of 43 percent of the images. PNG rose from 16 percent of graphics to 18 percent, and GIF dropped from 41 percent to 38 percent.
