Key issues and solutions for web page access speed
|
<br /> The website access speed can directly affect the website traffic, and the website traffic is almost directly linked to the website's profits. Therefore, the website speed issue has become a matter of great concern to enterprises and webmasters. There are more and more websites now, and the opening speed of many friends' websites is not ideal. Maybe you can open your website very quickly, but others may complain that it is slow when they open your website. This may be caused by line problems such as Netcom and Telecom, but most of the time it is due to problems with our website itself that affect the speed. How to improve the access speed of the website? Let's talk about some key issues and solutions. Many people use virtual hosts to build websites and store web page files in virtual space. However, once the page content increases, the website opens very slowly. If you encounter this situation, instead of looking for better space, it is better to optimize the web page code to achieve a satisfactory speed. The following summarizes some practical methods. When making a homepage, the following methods can greatly improve the speed of the web page. 1. Remember to slim down the page <br />Browsing the web page is actually downloading the web page content in the virtual host to the local hard disk, and then interpreting and viewing it with the browser. The speed of downloading web pages accounts for a large proportion of the display speed, so the smaller the space occupied by the web page itself, the faster the browsing speed will be. This requires that when making a web page, you should follow the principle of keeping everything simple, such as not using too large Flash animations, pictures and other resources. A clean and concise page gives people a sense of clear thinking. 2. If not necessary, try to use static HTML pages .<br />As we all know, programs such as ASP, PHP, JSP, etc. realize dynamic interaction of web page information. They are indeed very convenient to run because of their good data interactivity. They can easily access and change the contents of the database, making the website "dynamic", such as: forums, message boards, etc. However, such programs must first be processed by the server to generate HTML pages, and then "sent" to the client for browsing, which will inevitably consume a certain amount of server resources. If you use too many such programs on a virtual host, the web page display speed will definitely be slow, so there is no need to do so. Please try to use static HTML pages. 3. Don’t stuff the entire page content into a Table <br />This is a problem with web design. In order to achieve uniform alignment of the page, many webmasters stuff the entire page content into a Table, and then use cell td to divide the layout of each "block". The display speed of this kind of website is absolutely slow. Because the Table will not be displayed until all the content in it is loaded. If some content cannot be accessed, it will delay the access speed of the entire page. The correct approach is to divide the content into several tables with the same structure, and do not put all of it into one table. 4. Change the access of ASP, ASPX, PHP and other files to .js reference <br />This should be paid attention to when designing ASP, ASPX, PHP and other programs. If you want to embed dynamic data in a static HTML page, and this dynamic data is provided by ASP, PHP and other programs, you will use the following statement reference: In this way, every time someone visits your website, the server will execute and process the tongji.asp file once, extract the corresponding data from the database, and then output it to the web page for display. If there are tens of thousands of people visiting at the same time, it will be executed tens of thousands of times, and the consequences can be imagined. It is recommended to dynamically generate data into a 1.js file in these programs, and then reference the js file on the homepage through code such as <SCRIPT src=../../" http://www.aaa.com / your js file specific name">< /SCRIPT> In this way, the task of displaying data is handed over to the client's browser, which will not consume server resources and the display speed will naturally be very fast! 5. Use iframe to nest another page <br />For example, if you want to insert some advertising codes on the homepage of your website, but don’t want these advertising websites to affect the speed, then using iframe is the most appropriate choice. For example, to insert some advertising codes on the homepage of http://www.aaa.com/ , put these advertising codes on a separate page, and then embed the page on the homepage with the following code, so that the display of the entire homepage will not be delayed due to the delay of the advertising page. The code is as follows: <IFRAMEmarginWidth=0marginHeight=0src="http://www.aaa.com/ServerPart.asp"frameBorder=0width=468scrolling=noheight=60leftmargin="0"topmargin="0"></IFRAME> Among them, http://www.aaa.com/ServerPart.asp is the path of the referenced file. 6. Pay attention to the skills of placing website counter code <br />Placing a counter on a web page can count the website's access traffic and provide a basis for access for webmasters and advertisers. However, no matter how powerful a website statistics system is, there will be times when it fails. If you put the statistics code directly in front of the page content, or in a Table or div tag, then when the counter cannot be accessed, the Table or div on your page will cause a delay of tens of seconds, causing the page to take a long time to access. Therefore, to increase the speed of the website, you must pay attention to the location of the statistical code. The correct way is: put the statistical code at the bottom of the page, and do not put it in the same Table or div tag as the page content. You can place the statistics code directly at the bottom of the page code, or make a separate Table or div at the bottom to place the counter. This way, when the counter cannot be accessed, your website speed will not be affected in the slightest. 7. The Art of Friendly Links <br />Links between websites can increase the publicity effect of a website. Logo image links can more accurately describe the theme and positioning of the website, which will greatly enhance the publicity effect. However, too many image links will inevitably affect the display speed of the web page. Many webmasters like to directly quote the image URLs on friendly websites. In this way, the images have to be loaded before they can be displayed. The access speeds of various friendly websites are different, and the entire table cannot be displayed until all the images are downloaded. This greatly reduces the speed of the web page. Therefore, when making friendly links, you should try to: 1. Only make text links: Making text links will not delay the speed of the web page. 2. Put all the links into a separate page, and then link to that page on the home page. 3. If the friendly link must appear on the homepage, please put the entire Table containing the link at the bottom of the page. Because the page is displayed row by row from top to bottom, putting it at the bottom of the page will not delay the display of other content. 4. Download the LOGO image of the friendly link first and then upload it to your own web space. In this way, the speed is determined by your own website space and is not affected by the friendly website. 8. Selection of website space <br />If all the above methods have been used and the space access speed is still not ideal, then it may be a problem with the speed of your website space. When choosing a website space, it is recommended that you use dual-line space, so as to avoid delays caused by network problems when other users visit the website. |
