How to analyze GZIP, I believe that many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

What is GZIP?

Gzip is the abbreviation of GNUzip. It is a file compression program of GNU free software. It was developed jointly by Jean-loupGailly and MarkAdler.

GZIP coding on the HTTP protocol is a technology used to improve the performance of WEB applications. High-traffic WEB sites often use GZIP compression technology to make users feel faster. This generally refers to a function installed in the WWW server. When someone visits the website in the server, the function in the server will compress the web page and transfer it to the visiting computer browser to display it. In general, plain text content can be compressed to 40% of the original size. In this way, the transmission is fast, and the effect is that it will be displayed quickly after you click on the URL. Of course, this will also increase the load on the server. This function module is generally installed in the server.

Novice webmaster often ignores the important step of website visit optimization! An excellent website should not only have excellent content and perfect interface, but also have a good user experience, such as access speed, browser compatibility and so on.

The GZIP introduced in this article is to help webmasters understand and implement a way to enhance access speed, for example, the home page of a website has 1m, then users need to download 1m of data when visiting the home page, and if the home page is compressed with GZIP, the size of the home page is even smaller, assuming a compression of 50%, then there is only 512Kb, and the access speed is naturally accelerated.

There are many tutorials on how to open GZIP, which are not repeated here. You can test the compression results through http://tool.chinaz.com/Gzips/ (see figure)

Tip: GZIP can compress static files such as htm\ html\ css\ js\ asp\ aspx\ php, and the compression ratio varies according to the contents of different files.

Advantages: it can speed up the visit speed of the website and reduce the utilization rate of bandwidth.

Disadvantages: it will consume more CPU resources to compress web pages.

So after you set up, if your CPU usage is very high, please uncheck the HTTP compression check in the IIS- website-Properties-Service, and restart IIS. (it is recommended that the compression function should not be enabled for more than 10 stations on VPS)
