Building Highly Scalable Servers with Java NIO (4 messages) Developing a fully functional router based on I/O multiplexing was not simple. : Building Highly Scalable Servers with Java NIO multiplexing is significantly harder to understand and to implement correctly. use the NIO API (ByteBu ers, non-blocking I/O) The classical I/O API is very easy Java NIO Framework was started after Ron Hitchen’s presentation How to Build a Scalable Multiplexed Server With NIO at the JavaOne Conference .

You’re right I only tested bandwidth more important scalanle my problems and I don’t think I’ve seen anything about latency so far. Mads Nielsen 3 Think about switching electric current vs.

Bad news for us! Apache-MPM worker takes advantages of both processes and threads threadpool.
In addition, hundreds or even thousands of concurrent threads can waste a great deal of stack space in the memory. A pool of threads poll the queue for incoming requests, and then process and respond.

Understanding Reactor Pattern for Highly Scalable I/O Bound Web Server
Talk is cheap and show me the code: Actually, there are various ways to do this — different programming languages have their own libraries e. In the following code, a single boss thread is in an event loop blocking on a selector, which is registered with several channels and handlers. To answer these questions, let us first look at how an HTTP request is handled in general.
As to C async programing with async and await keywords, that is another story. After accepting the incoming request, the server establishes a TCP connection.

In terms of processing the request, a threadpool is still used. Unfortunately, there is always a one-to-one relationship between connections and threads.
To handle web requests, there are two competitive web architectures — thread-based one and event-driven one. And the operating systems themselves also provide system calls in the kernel level — e.
Email Required, but never shown. It reads and parses the content in the request from the socket CPU bound. This pattern decouples modular application-level code from reusable reactor implementation. The dispatcher blocks on the socket for new connections and offers them to the bounded blocking queue. Non-blocking avoids this sort of thing. That said, the point of Channel is to make this less tricky.
