A lot of webmaster and network companies do not take into account the speed of the site, the problem is simply to make the Web page, casually find a space hanging up even if completed. I think should first take into account the speed of the site, using pure manual coding, Div, CSS, sprites, gzip and other network technology and use of local server can greatly improve the speed of the site.
According to some sample surveys, visitors tend to think that faster-opening sites are more quality, more believable and more fun.
Correspondingly, the more slowly the page is opened, the more the visitor's psychological frustration will be felt, and the credibility and quality of the site can be questioned. In this case, the user will feel that there may be some errors in the background of the site, because for a long time, he did not get any hints. Also, slow opening speeds can make users forget what to do next and have to recall again, which further worsens the user experience.
Speed index is particularly important for e-commerce sites, the faster the load, the more easily make visitors become your customers, reduce customer selection after the goods, and finally give up the proportion of the bill.
There are several factors that determine the speed of Web Access:
1. Server performance.
2. The quality of the site itself, web code, website content, Web site development technology will affect the speed of the site open.
3. Visitor computer, network configuration.
4. Network conditions, such as bandwidth 512k,2m and optical fiber and network service provider differences (telecommunications, unicom).
Now focus on the quality of the site itself to the impact of the opening speed of the site.
1. Website Development Technology
As we all know, ASP, PHP, JSP and other programs to achieve Dynamic Web page information interaction, it is really very convenient to run, because their data interaction is good, can easily access, change the content of the database, so that the site "move" up, such as: Forum, message board. However, this kind of program must first be processed by the server, generate HTML page, and then "send" to the client browsing, this will have to consume a certain amount of server resources. If you use this type of program on a virtual host too much, the page display speed will be slow, so there is no need, please try to use static HTML page.
2. Web content
Because the entrepreneur to the website optimization understanding is not high, blindly pursues the website beautification effect. Therefore, most of the corporate site pictures too much, pictures too large, flash animation too much, the user access up very slowly, here we have to mention sprites technology, sprites is the site all the background picture and icon picture integration of a picture, by controlling the position of the background picture to achieve, The advantage is that it reduces the number of requests and can significantly speed up the page opening.
3. Web page code
The Web page code is not rigorous, redundant code is serious. How much the content of the Web page also determines the speed at which the site opens. But we think more important is the page content typesetting, layout way. Many corporate Web sites in order to pursue the unity of the page, the entire content of the page into a table (table), and then by the cell TD to divide the layout of each "block", the display speed of this site is absolutely slow. Because the table to wait for all the contents are loaded after the display, if some content is inaccessible, it will delay the entire page access speed. The right thing to do is to split the content into a few table with the same pattern, not all stuffed into a table, the best way is to use DIV to layout.
4.GZIP Technology
Gzip is on the server side of the Web page files compressed after the transfer, and then decompression on the client restore technology, can greatly save bandwidth resources and Web site open time, in the enterprise station and the general Web site to use this technology can achieve very good results.
