Ignore the sites telling you to set the value to “30.” Those same pages will also tell you to create a new value called “nglayout.initialpaint.delay” and to set that value to “0”. All this does is start displaying the information on the webpage sooner. nglayout.initialpaint.delay does not make your page load faster. In fact, it can make it load slower; especially on slower connections. If you create this value and set it to “0” you will notice the page beginning to render right away, but it will take longer to finish completely.
