2, small improvement to make the Web page display faster

After we find the reason why the Web page is slow, we can make some specific changes. Below, we give some common improvement methods to help people improve the speed of the website faster.

Using gzip compression Document: Gzip encoding is a way to improve the performance of Web pages, not only reduce storage space, but also reduce the time required for transmission. Using gzip compression for files in your Web site can significantly increase the speed of your Web page loading and reduce your bandwidth consumption.

Place the style sheet file on an external call: Place JavaScript and CSS style sheet files that need to be used on the page in a different folder so that the calls are cached when you open other pages of the site, speeding up the load on the site pages.

Avoid using page redirection: Whether through the server sanctity orientation or through JavaScript code for content redirection, the site will first load a blank page, and then directed to another page, which not only prolongs the load time of the page, but also very likely to lead to not jump, so that users face a " Blank page.

Clear repeat redundant script: browser loading the same Web script will increase the load time of the page, but many programs will have this simple error occurred. Take a look at the site for jquery or other scripts that have been invoked two or three times.

Reduce domain name DNS lookup time: When a user types a domain name in the browser's address bar, the browser locates the IP address of the domain name through the DNS system, while the DNS time is set at a lower level, such as a DNS query for the average 60~100 millisecond.

Weight loss for JavaScript files: This method differs from the gzip compression feature, and there are many ways to shrink JavaScript documents, such as removing unnecessary spaces. Reducing script files can significantly improve the speed of Web page access.
