With the advent of the era of unlimited Internet and ajax beauty, webmasters have ceased to care about the speed of loading pages. For example muzzle Habr weighs 750 kb . Not enough ? On my broadband, I would say imperceptibly, but do I need to spend 330 kb on images without compressing them at all? Now representatives of google started talking officially that speed matters. For me personally, this is not news, the whole question is about the resources of the programmer and the server, there are no other questions. But what remains to me is a mystery (advice in GWT): Minimize DNS lookups The domains of the following URLs only serve one resource each. If possible, avoid the extra DNS lookups by serving these resources from existing domains:* Go to URLhttp://www.google-analytics.com/ga.jsMinimize DNS lookups The domains of the following URLs only serve one resource each. If possible, avoid the extra DNS lookups by serving these resources from existing domains:* Go to URLhttp://www.google-analytics.com/ga.js Is this a joke or what ?!
