Node.js vs asp.net asynchronous pages

Question

still trying to understand n node.js ...

• If I apply the asyn.net async pattern for each I / O operation and set maxWorkerThreads = 1, is it (conceptually) similar to node.js?

• Is an I / O operation (in any framework) performed in its own thread, or is there any OS functionality for receiving notifications / light streams?

• this SO thread says node.js still uses threads internally, so this is not so different from asp.net. Some answers say yes, but this is the best programming model, etc. What topics does this easy I / O question refer to, like the ones I asked in # 2?

Answer 1

• See this similar question

• As for the implementation-specific I / O operations. The linux server uses libev, and the Windows backend uses IOCP. Watch this video at async i / o details for windows / linux

• node.js only uses streams internally because linux does not have an asynchronous I / O system (e.g. windows with IOCP). Thus, to make asynchronous IO possible, you need an internal thread pool. Watch the video.
