Node. JS features Single thread

In Java PHP or. NET, a new process is created for each client connection, and each process consumes about 2MV

Memory, that is, theoretically a 8GB memory server can simultaneously connect the maximum number of users to 4000

To allow the Web application to support more users, you need to increase the number of servers and

The cost of hardware for Web applications has certainly risen.

NODE.SJ does not create a new thread for each client connection, but only uses one thread, and when a user connects, it triggers an internal event, through

nonblocking I/O is an asynchronous, event-driven mechanism that allows node. JS programs to be macro-parallel, using node. SJ, a

8GB server that can handle links with more than 40,000 users at the same time, plus the benefits of single threading

There are also operating system security and thread creation, destruction of event overhead,

Re-entry, single-threaded benefits, and the operating system is completely no longer wired to create, destroy the time overhead, in fact, node. JS is suitable for doing some

Io is more of a thing, a 8Gb memory server that can handle more than 40,000 user links at the same time, how can you simultaneously handle

In this way, we can see our request header in the downstream request, and request the type of the document to the specification.
