What is the number of IIS server connections

IIS server is a basic Internet service provided by Microsoft based on Microsoft Windows. It was originally an Optional package for the Windows NT version and was subsequently released together with Windows 2000, Windows XP Professional, and Windows Server 2003. However, IIS is not available in the commonly used Windows XP Home version.

IIS server supports HTTPHypertext Transfer Protocol, Hypertext Transfer Protocol), FTPFile Transfer Protocol, File Transfer Protocol) and SMTP Protocol. IIS can be highly expanded by Using CGI and ISAPI.

The IIS server supports language-independent scripting and components. through IIS, developers can develop a new generation of dynamic and attractive Web sites. IIS does not require developers to learn new scripting languages or compile applications. IIS fully supports VBScript, JScript development software, and Java. It also supports CGI, WinCGI, and ISAPI extensions and filters.

The number of IIS server connections refers to the number of accesses from the IP address to port 80, that is, the number of website files called, not the same as the number of simultaneous online users.

I can introduce the number of IIS server connections as follows: if a door is 4 meters and each person's average width is 0.5 meters, 8 people can pass through the door at the same time, that is to say, the IIS server for this portal is 8. In 10 minutes, 100 people may pass through this portal, so the number of online users for this forum may be 100, and the IIS server is 8, does it mean that eight people can request data in real time at the same time?

No. Because the program is different, the number of IIS servers occupied by each program is also different. It may be a 2-meter-wide fat man who can only allow two people to pass at the same time. That is to say:

(1) The number of units requested by the IIS server at the same moment. This is not equal to the IP address.

(2) an IP address may occupy multiple IIS servers at a time. For example, a fat man occupies four other IIS servers.

(3) the IIS server refers to the number of concurrent threads, while the online statistics refer to the total number of concurrent threads. The other is the number of concurrent threads, one is the number of people who enter the door during this time period.
