current virtual hosts are divided into three categories:
one, traffic restrictions: that is, direct restrictions on network traffic, this restriction is usually the most severe kind of restrictions, the 10 G traffic generally support 50 people online. After the flow exceeds that month, the site can not normally visit in a month, the solution is to upgrade the space or increase traffic.
two, CPU CPU did not appear to limit limit limit: IIS or network traffic, but because each program requires a certain CPU quota, is a disguised form of traffic restrictions, "usually suggested online too much is due to the CPU limit caused by too small. Refresh or 15 seconds after you can get temporary normal operation, about 1% of the CPU limit equivalent to 20 IIS connections. This is very important for the forum space. Once the CPU limit of the forum is too small, it will not work properly.
three and IIS restrictions: IIS restrictions are now used most, and are also accepted by most users or mainframe vendors, and are relatively loose traffic restriction schemes. Typically, 20 IIS are equivalent to 1%CPU occupancy.
in short, the virtual hosting is virtually unlimited, and the overall population is divided into the above three ways, and how you choose depends on your needs. If your program is optimized for the CPU little program, you can choose the CPU, so you can get the biggest play online; if you are a beginner, or forum users, or website program in BBS, select the IIS limit or direct flow restriction is a good choice.
attached: detailed explanations on the number of simultaneous connections and the number of people on the line
1, the browser visits the site and must establish a connection with the site through the TCP protocol. This connection exists when the information is read from the server and is automatically closed at the end of the read. So, when a page has been completely displayed on the client’s monitor, the connection used may have been closed.
2, when each visitor visits a site, may take up 1-3 connections, which are automatically processed by the computer, in order to speed up the connection. So, for the basic type of connection number for 30 hosts, sometimes only a dozen people to visit, not surprising.
3, the number of online people in the forum is based on the number of people visiting the forum in a given period of time, and is not directly related to the number of connections. For example, the DZ forum, the default seems to be 15 minutes of activity time may show a number of forums, users online, but http://s.508z.com users because of (positive) in the read data in the forum, so it will not occupy the number of connections. So, as long as the viewer on the forum visit is too concentrated, will not be at a point in time exceeds the maximum number of simultaneous connections, and statistics of the number of online forums, will greatly exceed the maximum allowed number of concurrent connections for space. Some users show the popularity of the forum, >
