Aliyun what are the factors that affect the opening speed of the website

　　Factors that affect the opening speed of a Web site

The size of the Web page content

The size of the Web page file is whether the site can quickly open the most important factor, if the server and other hardware, we can not decide, I strongly recommend from here, whether it is a table, or DIV+CSS, the appropriate optimization code, can reduce the size of the page. Try to optimize your code, with minimal code, and don't include the entire content in a box. At the same time, a large number of errors, redundant code is slowed down one of the Web site speed.

Configuration of the Machine

Including server-side and client-side hardware configuration level, the same network environment, dual-core server computing power is stronger. The same network environment, with a Celeron machine and Ben four duo processor computer, open the same Web page, the speed is certainly different.

Server Software

The amount of software, stability, and proper configuration of the software affect the server environment, which can affect the speed of the network. The server installs the software firewall, will sacrifice some network speed, therefore the VPS, or the independent server user installs a firewall can.

Network Minimum bandwidth

This is the most important factor, the slower the site to put on the good bandwidth to access the same speed as fast. The bandwidth of the network includes two locations on the server bandwidth and the user end, and the contact point is the outlet end and the entry port (for example, the docking points of Telecom to Netcom). The other is the user's own minimum bandwidth, if the user access to handle broadband low also affect access speed.

A large number of database operations

Small web site in the execution of a large number of database operations, will also affect the speed of Web site opening, the use of aps+access structure of the site is particularly obvious, especially at the same time a large number of users submit comments, the operation of the database lock, resulting in the site can not open.

With a lot of Javascript

The use of a large number of JS Web site is taboo, not only the search engine can not be included, and will continue to submit requests to increase the server burden, such as mouse effects, column effects, status bar effects and so on. The principle of these effects is to first download the server to the local machine, and then run it on the local machine, then you can see the effect. Special effects do too much, on the local machine will run for a long time to complete, and if your host configuration in general, it is more slow. Therefore, it is recommended to use less Javascript effects.

Page with large pictures and Flash

Pictures are the most important factor in slowing down speed. Pictures take up a lot of space, but also make the site open speed become very slow, the same flash is also a truth. It is recommended that the picture be processed so that the picture space becomes smaller.

Too many references to the contents of other Web sites

Including the reference to other sites of pictures, video files, etc., if the page directly referencing other sites, and the speed of the site is slow, or the site of the page no longer exist, then open the speed will be very slow.

DNS resolution Time

DNS resolution includes the number of round-trip resolution and the time spent on each resolution, both of which are the amount of time that DNS resolution consumes, so many people ignore the DNS problem, in fact, DNS on the Web site resolution speed is also very important.
