How Much Time is Wasted on Loading Unnecessary Data

Let's find out... How much time is wasted on loading > What in the world is this unnecessary data?! unnecessary data? Many of the top 1000 sites use improperly scaled or unoptimized images: If you've ever zipped a file, you know that you can reduce filesizes with compression. HTML, JavaScript and CSS files may contain stuff like whitespace, indentation, and/or comments, which makes it easier for develop- ers to maintain, but of course increases filesize! We analyzed the top 1,000 websites' on the Internet to find out how much extra data visitors are needlessly downloading. Web developers can serve you HTML, JavaScript and CS files in the same way! - Images that are resized by HTML/CSS As regular ol' web surfers. we don't need to download these extras! Instead of sending raw, uncompressed files, a server can send to you a zipped ver- sion that is smaller, and therefore faster to download! - Using an inefficient format - Exporting at too high a quality setting > Minify HTML/JS/CSS Using 3 very basic optimization techniques..." Minifying removes the extras and reduces file- size so that only essential code is downloaded by the visitor. > Enable Compression > Optimize Images Uncompressed files take longer to download By pre-scaling images and using free tools like Smush.it, jpegtran, or PNGOUT, web developers can still serve a nice quality image, but with a smaller filesize! Minify it! .we discovered that there was: 23,000,000GB Compression makes downloads faster! More kb Less kb of useless data being downloaded each month! How much data is this really? 5,750,000,000 songs > In 619 years, a single person could have: 75,000,000 movies ...she's just a girl who says that II AM THE ONE! 619 $88,357,230.05 Listened to "Billie Jean" 154 Undergrad degrees Flown around the world 80,932 times (If you put $1 in a bank account @ 3% interest compounded yearly) 65,069,280 times It would take 1 person on a standard DSL line... to download it all! > With 5,422,400 collective hours: Of course, no one person is doing this... but we as a COLLECTIVE GROUP are! Bart hasn't said "Cowabunga in a looong fime. Alas, poor Yor- BLUE 52!!! HUT HUT HIKE! 619 years works out to be What could we do instead? "Kwijibo' isn't a real word?! 5,422,440 hours Starting lines of the New Orleans Saints could perform Hamlet We could build 77% of The pop. of Rhode Island could watch the entire 1st season of "The Simpsons" We could all play Google Pac-man! (We actually did for 4.8 million collective hours that glorious day) of collective effort spent downloading useless data. 70,421 times Empire State Buildin g The worst of the Top 1,000 As of June 23, 2010, the the lowest Page Speed and YSlow scores belong to... * Tsk tsk tsk... Lowest YSlow score: Lowest Page Speed score: Forbes www.forbes.com www.mcafee.com (39%) F (51%) E Total page size: 1.18MB Total page size: 641KB After compression: 518KB After compression & img optimization: Everybody deserves a fast web experience. 334KB 662kb saved! 307kb saved! Ok fine, we may not end up building a skyscraper, but we can each do something a little more interesting than watching a site load longer than it has to!
