- 60. Web-based performance analysis usingthe „Google factors”.. https://developers.google.com/pagespeed/
- 61. Detailed in-browser performance analysis (req.Firebug Add-on)
- 62. #1 Get ridof multiple CSS & JS files 8 JS + 4 CSS req. on a single page is a bad idea! Best case: 1 CSS + 1 JS file. Real world: 1-2 CSS, 1 int. + 2-3 ext. JS Often times JS does change the style, so always do CSS before JS! Move CSS to the top, JS to the footer to un-block rendering!
- 63. #2 Do CSSSprites http://spriteme.org/ Combine multiple (small) images into one big image to save on HTTP requests.
- 64. Tip: Make imageseven smaller! Use tinyPNG to optimize PNG files without loosing in quality (up to 70% savings) JPEGmini does the same for JPEG files and will reduce your images massively (up to 80% smaller)! http://tinypng.org/ & http://www.jpegmini.com/
- 65. #3 Minify CSS& JS files Removing unnecessary whitespaces, line- breaks and comments to reduce file-size. And: Makes it way harder for competitors to steal your code! For CSS, try: http://www.phpied.com/cssmin-js/ http://developer.yahoo.com/yui/compressor/ For JS, go with: http://www.crockford.com/javascript/jsmin.html https://developers.google.com/closure/compiler Minifying this (small) style- sheet results in 63% savings!
- 66. #4 Enable GZIPcompression Output compression does massively decrease file-sizes and therefore speeds up rendering. Verify by checking the response headers, for “Content-Encoding“ to be set to “gzip“ One of the ugliest sites ever: http://www.gzip.org/ On Apache, try “mod_deflate” which is straight forward: AddOutputFilterByType DEFLATE text/html text/plain text/xml
- 67. #5 Setup cachingfor static resources It’s important to specify one of Expires or Cache-Control max- age, and one of Last-Modified or ETag, for all cacheable resources. Set the “Expires”-header to exactly one year ahead of the request date Set the “Last-Modified”-header to the date the file was last modified Set the “Cache-Control: max-age”- header to “3153600” (1 year, again) Expires: Fri, 07 Sept 2013 03:18:06 GMT Last-Modified: Fri, 07 Sept 2012 03:18:06 GMT Cache-Control: max-age=3153600
- 68. #6 Use Google’sCDN for popular libraries Google has the fastest CDN on the planet, make sure you use their DCs to serve your files if possible! https://developers.google.com/speed/libraries/ Since a lot of site-owners are using G-DCs, chances are, people have those files cached already!
