Fast speed but slow to open web pages and solutions

　　A brief summary of the reasons for the slow opening of the Web page, mainly has the following points:

　　First, the network minimum bandwidth

This is the most important factor, that is, netizens often say that broadband is not enough. The same Web site, if the broadband high, access speed will be significantly faster.

The bandwidth of the network includes two aspects of the server bandwidth and the bandwidth of the client, the point of contact is the outlet and the inlet (for example, the joint of Telecom to Netcom).

　　Second, DNS resolution speed

DNS resolution is the resolution from domain name to IP. People are accustomed to memory domain name, but the machine only recognize each other IP address, domain name and IP address is corresponding, the transformation between them is called Domain name resolution, domain name resolution needs to be specialized domain name resolution server to complete.

DNS resolution includes the number of reciprocating resolutions and the time spent on each resolution, and their product is the total time spent in DNS resolution. Many people ignore the DNS resolution factor, in fact, it is also very important to the speed of the Web site resolution.

　　Third, server and client hardware configuration

In the same network environment, dual-core server computing power must be stronger. Also in the client, the same network environment, you use a configuration of the Intel® i7 processor and i3 processor to open the same page, the speed must be different.

　　Four, Server Software

On the server side, the number of software installations and the stability of the operation will affect the server environment, which in turn affects the network speed. For example, a server configuration software firewall can cause network speed to be affected.

　　Five, page content

If your Web page contains a large number of unprocessed pictures, and these pictures are large, they can cause slow opening. Other such as Flash and video files, will affect the speed of access.

At the same time, redundant code is one of the factors that slow down web site speed. Webmaster needs to optimize the code, with minimal code, to achieve the best results.

　　VI. Database Operations

Small sites do database operations will also affect the speed of the site, especially at the same time many users submit comments, the operation will occur when the database lock, resulting in the site can not open.

　　Seven, use javascript effects

The use of JavaScript effects on the site is taboo, not only can not be crawled by the search engine, but also because of the constant request to the server, resulting in the burden of adding servers, the site slowed.

Specific examples such as mouse effects, program effects, status bar effects, and so on. The principle of these effects is first downloaded by the server to the user side of the machine, and then run on the local machine, and eventually be seen by users. Special effects do a lot, users on the local machine on the operation of a half-day ability to complete.

　　Eight, too much reference to other Web site content

For example, refer to other websites of images, video files and so on. If the link to the site is slow, even if the site does not exist, then the user to open the page will be very slow.

Other factors, such as the interconnection of broadband network in China, the domestic and south of the exchange of servers will have a delay phenomenon, directly affect the user's Web Access experience.
