So the efficiency of Web pages is definitely the most noteworthy aspect. Although we have 14 guidelines on how to improve the efficiency of web pages in the 14 guidelines on how to improve the efficiency of Web pages, how do we know how efficient our web pages are? At what level? What are the areas that have not been well done and need to be improved? Perhaps, you will say, ask the user not to know? But rational tools and data are more persuasive than the perceptual proportions that account for too much user experience. This article will introduce you to a tool to evaluate the efficiency of the Web page--yslow (why slow, the name is too good).
Yslow
YSlow is a firebug based plug-in released by the Yahoo developer team. And Firebug is a Firefox based plug-in. Therefore, YSlow is a plug-in based on Firefox Plug-ins. Although a bit around, but the final explanation of the problem is:
Unfortunately, Microsoft's IE series browsers cannot use YSlow.
YSlow can only be used on Firefox browsers.
If you want to use YSlow, then you must install Firefox first.
If you want to use YSlow, then you need to install the Firebug plugin on Firefox.
This may seem a bit depressing, but in fact it's not as troublesome as it seems, as long as you follow the steps below to quickly use YSlow:
Download the latest version of Firefox to http://www.mozilla.net.cn/firefox/and install it. Of course, if you've already installed Firefox, you can skip this step.
Download the latest version of Firebug to https://addons.mozilla.org/en-US/firefox/addon/1843/and install it. Of course, if you've already installed Firebug, you can skip this step.
Download the latest version of YSlow to https://addons.mozilla.org/en-US/firefox/addon/5369/and install it. Of course, if you've already installed YSlow, you can skip this step.
