Introduction

Not everyone can use a high-speed Internet connection. Even if everyone is able to use a high-speed network, it can make your WEB application look slow for a variety of reasons. In this era of increasing broadband speed, you should focus on the page load time. Shorten the precious page load time by a few seconds and shorten the more valuable requests and response times by a few milliseconds. You will create a better experience for your visitors.
After reading this article, you will be able to better understand the basics of Web page load time optimization. You can also use tools and knowledge to better identify and determine the slow loading of page parts and bottlenecks.

For

Ideally, you should have Mozilla Firefox installed. You should also have a broad understanding of WEB development. The topics covered in this article are not complex, but if you are aware of topics such as Hypertext Markup Language (hypertext Markup language,html), cascading style sheets (cascading style sheet,css), and the programming language, It will be more handy to learn this article. You do not need to use the integrated development environment (IDE), just use your favorite editor.

You must have JavaScript enabled in your browser. In addition, to learn about Firebug and YSlow-related content, you need to install the Firefox Web browser.

Suppose you don't have broadband

Many people access the Internet through some form of broadband connection, which may be DSL, cable, fiber, or other methods. However, users who cannot use this type of technology have to use dial-up connections. You must have forgotten what it feels like to dial up, but you can try to think back to the page load-by-line scenario.

Luckily, these poor people are now able to get some help. You can improve their experience by shortening the time to load pages. However, dial-up connections are not the only reason to reduce load and response speed. Many web designers mistakenly believe that the advent of high-speed Internet connectivity makes Web site performance optimization unnecessary. This view is wrong. For example, many of the tasks that you used to perform with desktop software can now be performed online. It's very difficult to get a high-speed response experience like desktop software in a WEB application, so performance tuning is important. Fortunately, some tools and best practices can be used to shorten response and load times and provide a smoother experience.

Basic Tools

For all optimization-related tasks, you must use tools to diagnose bottlenecks and identify problems. The two most widely used tools in WEB development today are Firebug and YSlow, which are open source, free Firefox plug-ins.

Firebug
Firebug (see Resources) is one of the most popular Firefox extensions that can make WEB developers work easier. It contains a number of very useful features, such as:

JavaScript debug JavaScript command line monitor JavaScript performance and tracking xmlhttprequests login Firebug Console trace check HTML elements and dynamically edit HTML code dynamically edit CSS documents

YSlow
YSlow (see Resources) analyzes Web pages and tells you why Web pages are slow to load, based on the High performance Web site rules drafted by Yahoo! (see References). YSlow is an integrated Firefox plug-in with Firebug, so you need to first install Firebug before you can install and use YSlow.
