IIS limit, comparison of flow restrictions and CPU restrictions The current virtual host is mainly divided into three types of traffic restrictions: 1: The traffic limit is directly restricting network traffic, which is usually the most stringent flow limit, 10 g traffic Most support 50 people online. After the month, the website does not have access to the website in one month, the solution is to upgrade space or increase traffic! Second: CPU limit CPU limit does not limit IIS or network traffic, but due to Each program is running requires a certain CPU quota, which is also a changeable traffic limit. Usually the online excessive online is due to the excessive CPU limit! You can get temporary normal operation by refreshing or 15 seconds, usually 1% The CPU limit is equivalent to 20 IIS connections! This is important for the forum space. Once the CPU limit of the forum will not run normally! It is the only loose flow limit, usually 20 IIS is equivalent to 1% CPU, in turn, the virtual host does not actually be unlimited, the total can be divided into three ways, how do you choose, you have to see you Need, if your program takes up the CPU, it is an optimized program to select the CPU, so your online can get the biggest play, if you are an initiator, or forum users, or BBS in the website program, Choosing IIS restrictions or direct traffic limits is a good choice! About the simultaneous number of connections and online number issues Many users have ambiguous concept understanding of the number of connections, now the following: 1, the viewer access the site, required to pass TCP protocol, establish a connection. This connection exists when reading information from the server. When reading, it is generally automatically turned off. So, when a page is fully displayed on the client's display, the connection may have been closed. 2. Each viewer, when accesses a site, it may take up 1-3 connections, which is automatically processed by the computer, so the purpose is to speed up the speed. Related questions: Therefore, for the basic type host for the connection number 30, sometimes more than a dozen people can be accessed, it is not enough. 3. The number of online people in the forum is the standard of accessing the activities of the forum in a certain period of time, and there is no relationship with the number of connections. For example, the default seems to be the number of activities in 40 minutes (? Maybe the forum shows a user is also online, but this user does not take up the number of connections due to not (positive) in reading the forum. Related questions: (1) So, as long as the viewer's access to the forum is not more concentrated, it will not exceed the maximum number of connections at a time point. The number of online people in the forum will greatly beyond the maximum number of connections allowed by the space. . (2) In order to display the popularity of the forum, some users can mark the time range of the number of online people in the forum (the mobile network forum provides this feature), and even all those who browse your site in one day are as an online number. 4. Although the server can specify the maximum number of connections for each site, there is also a total maximum number of connections for the server. Therefore, even if the maximum number of connections in the user site is not limited, the site is still unable to access the site when the server reaches the maximum connection. The maximum connection between the server is generally at 1000--2000. Related questions: (1) This is why the service business dares to open an unlimited connection number, essentially an infinite connection. (2) The main unit provided by the western digital, allowing the number of connections to be higher, should meet the user needs.
5. In the current hosting service, some service providers use many people to blur the above concept, and mislead consumers, so buying hosts should be cautious, what is the number of IIS connections IIS connection Number refers to the number of connections, what does it mean? It is necessary to divide a few cases: (50 people online as an example) A user download your file, after the end, it is correct, which is calculated in an instant, that is, you can accept the 50-person website. 50 points Download b Users open your page, even if you stay in the page, you have no request to the server, then you must count online within 20 minutes after the user opens, that is, you can do the 50-person website for 20 minutes. Accepting Different Users Open 50 Page C The case of the user continues to open other pages of the same website, then the number of online people will calculate after the last click (issuance request), in this 20 minutes, regardless of whether the user hits this 20 minutes ( Including a new window to open) or one person online. D When you have a frame (iframe) in your page, then more than one frame is more online! Because this is equivalent to requesting multiple pages to the server at the same time. E When the user opens the page and then close the browser, the number of online people's online number will be cleared immediately. Then understand what is the number of forums online. The forum online is only calculated to calculate the number of activities within a certain period of time. The time users here can set themselves, the mobile network forum defaults to the relative accuracy of 40 minutes. According to the above description, it is obvious that the concept of online and IIS connections does not match the number of IIS connections and the forum online does not match? The specific analysis is as follows: 1: You use the plug-in version of the forum or beautify the Forum! The current plugin is very rubbish, not only accounts for server resources, but will make the forum slow down (no plugin can be more than double), and it is very popular, and some plugins call a lot of frames, less 2, 3, more 4, 5! Even online playing music, so a person is quite online online! The beautification version of the Forum is also the same as the quantity of IIS than the standard version of the forum.
