You can do this right in the browser.<\/li>\n<li>Use online tools to measure more advanced site performance metrics and compare them against industry average.<\/li>\n<li>Know how long your page takes to finish rendering and what the time is to the first interaction. This is your first-impression metric.<\/li>\n<li>Evaluate your business goals and try to correlate site performance with traffic, conversiones, revenues, or whatever metrics is relevant to your business.<\/li>\n<li>Count all of the components that have to be requested to render your page Can you reduce this number?<\/li>\n<li>Slim down your HTML. Combine and minfiy your CSS files.<\/li>\n<li>Take a close look at where you reference scripts and when they excecute. Are scripts blocking page rendering or interaction?<\/li>\n<li>Make sure you&#8217;re using images wisely and optimizing them for size and quality. A little bit of code can make sure you&#8217;re not sending too many image bytes where they&#8217;re not needed.<\/li>\n<li>Don&#8217;t throw out social features just because they add to your request, scripts, and page size if they benefit the business; just be sure to use them tactically instead of spreading them all over the place.<\/li>\n<li>Starting with a focus on the mobile experience \u2014most likely your fastest growing customer experience\u2014 may help you target performance optimizations that benefit all visitors to your site, even those using the desktop.<\/li>\n<\/ol>\n<footer><a class=\"title\" lang=\"en\" href=\"http:\/\/www.oreilly.com\/webops-perf\/free\/webpage-size-speed-perf.csp\" hreflang=\"en\">Web Page Size, Speed, and Performance<\/a> \u2014 <cite>Terrence Dorsey<\/cite><\/footer>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Acabo de leer el \u2014brev\u00edsimo\u2014 libro Web Page Size, Speed, and Performance, escrito por Terrence Dorsey y publicado por O&#8217;Reilly (la descarga es gratu\u00edta).
