akamai web acceleration

I collected some information about website acceleration and made a seriesArticleIt may be switched to or from the network. (1) graphic processing for web page Acceleration In the process of website maintenance, you may have encountered such a situation: pages created after hard work, but there are too many images, and the webpage structure and table structure

needs to work again, the complex content management system decomposed into: content input and caching of these 2 relatively simple system implementation.Background: Content management system, focus on the content of the release to do, such as: Complex workflow management, complex template rules, etc. ...Foreground: page cache management can be implemented using the caching systemSo after the division of labor: Content Management and Cache Management 2, no matter what the optional space is very

layer technology to eliminate node device congestion caused by peak data access. The cache server has caching capabilities, so most Web page objects (Web Page object), such as HTML, htm, PHP and other paging files, gif,tif,png,bmp and other file formats, in the validity period (TTL), for repeated access, You do not have to re-transfer the file entity from the original site, simply pass the simple authentic

of different characteristics, performance bottlenecks are often different, the required web acceleration strategy is not the same. static content (small file). For example, a variety of picture content, the required bandwidth is relatively small. The site handles bottlenecks in IO concurrency. Therefore, you can choose a lightweight Web server that su

Kanwi.cn has a web server with a daily traffic of about 0.1 million. There are several virtual hosts on it. recently, Squid2.6 has been installed for WEB acceleration. Squid and Apache are both on the same server. The effect is very obvious, many people on the forum asked how to configure squid2.6 support. The VM now posts the installation process with everyone.

Some time ago, according to the video effect of the United States to write a similar effect of the web version of the animation.There are three types of browsers installed on your computer: IE, Chrome, Firefox. Tests were made, and the results showed that Chrome renders the worst in this respect. There is often a phenomenon of Dayton. FF behaves best.have been baffled, especially before using the canvas label to make the image filter effect, the Chrom

, so the user requests the first jump to the CDN server, when the CDN server cache the user requested data, you can return from the CDN directly to the client browser, the shortest path return response, Speed up user access and reduce load pressure in the data center.CDN can cache the general Css,js pictures and other static resource files, and these files are accessed very frequently, caching them in the CDN will greatly improve the website's access speed.But because the CDN is deployed in the

architecture revision. We still remember that the 80-90% end user response time was spent on various elements on the download page, such as files, style sheets, scripts, and Flash. Instead of focusing on restructuring the system, it is better to distribute static content first. This not only greatly reduces the response time, but also facilitates the distribution of static content due to the presence of CDN. CDN is a collection of geographically distributed

scripts, cache opcode, and do not parse the original script every time. The server script parser runs a cache of opcode, which is much more efficient than parsing the original script directly. This is why the Php/python parsing engine needs to compile the original script into opcode, and then through the virtual machine to resolve the cause of the execution, so that it can achieve the same performance as Java, C #. More transformations, the root cause is to improve performance. Accelerates data
