How important is the website opening speed? At least, such as the current Google Baidu, such as mainstream search engine, has been the speed of the site quality assessment scope. From the user point of view, open the Fast Web site, reducing the waiting time for customers, naturally will undoubtedly get the user's favor. So increase the speed of Web site loading, to a certain extent, is to improve the user experience. Many companies do not hesitate to spend heavily on the search of the Soviet engine on the investment bid ads, the results are, in some cases, keyword ads are clicked, advertising costs are consumed, but the site has been slow to open. Not consumption of advertising costs, but also to create a bad impression on users.

Causes the website to open the load slow reason many, many times is caused by the server instability, also has the engine room line problem to bring the reason. and the Web site itself program to write the specification or not, the same will affect the site load speed and operation stability. Whatever the cause of the slow loading of the site, the results are the same, will let users feel the site has problems, or even magnified for the company management problems. Therefore, the speed of the site is definitely not a trivial situation, even more than the site construction, more important than site optimization. Because that is the basis, only stable and rapid operation of security, can be sophisticated design presented.

I. Web site programming is not standardized

Now many sites are based on dynamic interactive technology development, to a large extent, to facilitate the maintenance of site content updates. However, Dynamic Data access technology is bound to use a lot of judgments, loops and conditional statements. A little attention will cause the judgment statement forget the end, loop statements forget to close and so on. Another typical negligence is that when reading and writing data, the database opens and forgets to close. This will cause the Web site to run slowly, even if it does not work properly and so on. For example, sometimes, after the death cycle, the Web site opened after the constant consumption of server resources, resulting in the Web site can not run.

Code is not standard another performance, is the site code is not concise, code bloated and waste code serious. We know that the browser to send a request to the server, it is necessary to resolve the dynamic server-side page into the browser executable HTML, sent to the browser to display to the user. The simpler the code, the smaller the volume, the shorter the time it will take in this data transfer, although the time is short to be computed in milliseconds. Because the table layout has nested problems, if the page file is larger, it will slow down the page load speed, the ideal layout of course is div.

Second, the server line and configuration is poor

The web site is slow to open, largely due to the inability of the server to run stably. Now every place, there are many engaged in the server leasing hosting enterprises, because of the room, line resources and server configuration, the price difference is also very large. Is the same as a computer room configuration of the server, the host on the number of sites to open, but also affect the quality of the site and stability. Compared to the development of Web site construction, every tens of millions of million, the server (especially the vast majority of enterprises are using the virtual host) can be negligible to negligible costs.

But the server in the Web site to play the role is not general, the server is the cornerstone of safe and stable operation of the site and rely on, the vast logarithm of the site cloud new instability is the root of the server. Therefore, the website construction production must choose the high quality service device, but is not only the price high and the space size to judge. As a general company, it is impossible to understand the server configuration and technical standards too deeply, and the choice of higher profile companies become a shortcut. Select the server also need to grasp the point is that, due to the existence of domestic interconnection phenomenon, as far as possible to choose a dual-line or multi-line access to the server. So whether the south or the north, whether Netcom or telecommunications, access speed will be the same fast.

Third, picture animation and special effects too big

Both animations and pictures need to be downloaded locally before they can be executed. If the picture or animation is too large, will naturally slow down the site loading process, open speed is much slower. Because the display resolution is only 72dpi, so in general 100K around the picture is enough to use, in the case of the quality of the picture to ensure that the size of the compressed picture, is to improve the speed of the page load effective way. If it is not possible, the proposed site to use a small amount of flash, the animation not only need time to load, slow down the speed of the site, but also can not be identified by the search engine, not conducive to the later site optimization.

Remove pictures and animations, there is a more resource-intensive is some special effects, especially the JS code to write some special effects. For example, now more popular jquery some plug-ins, there are other navigation bar and image playback Plug-ins and so on. While the code is streamlined, it consumes a lot of resources from the server and slows down the page load. In the picture and special effects, there is a relatively easy to ignore the place, is the general Web site above all have picture scrolling, such as on the homepage recommended products. What many people overlook is that there is no limit to the number of scrolling pictures, which slows down the opening of the site.

Four, the website virus is hanged the Trojan horse

The other reason why the Web site is slow to load is the virus in the server and the Trojan horse. A lot of the pages are hung Trojan, the way to hide the code, embedded executable virus files, when users browse the Web when the virus trojan is automatically downloaded automatically installed. and the virus Trojan downloading installs the process, the webpage other file is unable to load, will bring the website to open the speed surprisingly slow. The root of the virus in the site should be linked to Trojan Horse is to standardize the programming of the Web site program, to eliminate the obvious web site procedures and server Setup vulnerabilities.

No absolute security, everything is relative, including Web site programs and server settings. The best way to solve the virus in the Web site is hanging Trojan, is the data regular security backup, found problems in a timely manner through the backup file recovery. The general server is set up with a regular backup mechanism. The virus in the Web site after the Trojan is not only the removal of virus Trojan so simple, but to find the site program or server security settings weak links, and targeted to improve the adjustment.

Five, too much content database huge

This reason is neglected by many people, but it is true indeed. As the vast majority of corporate websites are now aceess small databases, the number of data read and write Exchange is strict. In general, small Web sites read and write tens of thousands of data access can be fully supported, but more than 100,000 or more, its efficiency is greatly reduced. And when the database volume reached more than 30M, read and write retrieval speed will be greatly reduced. Corresponding, the website data loading speed, the page opens the speed to drop dramatically. Many sites, especially many small sites can not find the reason for slow running, and check the database may be suddenly enlightened.

The solution to the huge database data exchange speed is slow, the only way is to upgrade the database. Because access is only suitable for small Web sites, you must use large databases, such as SQL, if the data exchange is larger. Professional website Construction company Pilotage Technology (www.joyweb.net.cn) prompts you, in fact, in the Acess database there is a compression repair tool, the actual operation also proved that the database after compression repair, can effectively reduce the size of the database. But this is only a drop in the bucket, a temporary mitigation method, for a long time, if the data exchange volume is large, or must upgrade the database.
