cluster module allocates requests through the Round-robin algorithm, which is good when the request delay changes very small, such as:But when there are different types of requests that take different processing times, it is less useful. Subsequent requests must wait for all previous requests to complete, even if another process can handle them.A better distribution model should look like this:Because this minimizes the wait time and can return the response more quickly.This can be done by putt

network Transport protocol, the HTTP server simple point is to return to the client page of the server.asynchronous I/O and event-drivennode. JS maintains an event queue during execution, and the program enters the event loop at execution time waiting for the next event to arrive.After each asynchronous I/O request is completed, it is pushed to the event queue for processing by the program process.For exam

-blocking operation: EXEC (). EXEC () it executes a shell command from node. js. In the example above, we use it to get all the files in the current directory ("Ls-lah"), and then output the file information to the browser when the/starturl is requested.The above code creates a new variable content (the initial value is "empty"), executes the "Ls-lah" command, assigns the result to the content, and finally

programmers don't seem to realize how bad the eval () problem is.Send a small amount of data continuouslyNode brings new ideas for architecting applications, and we can use the event model to architect Web applications, or "small" event models, based on node. In other words, you should send a large number of requests based on a large number of events, each with small packets of data, or fetching small amounts of data from the background as needed, ra
