In part 1, we developed a simple single-threaded HTTP server that processed requests synchronously. In part 2, we modified the server so that each request was handled in a separate thread, which improved concurrency but increased the load on the CPU and memory. In this article, we'll modify the server to use a ThreadPool which will help to improve concurrency while reducing the CPU and memory usage. Read more.

In part 1, we developed a simple single-threaded HTTP server that returned a static string. While single-threaded servers have their use cases, they lack scalability. The nature of a single-threaded server means it can only process one request at a time. If there's a request that's taking a long time to process, all other requests will be blocked until the slow request has been completed. If we want to handle multiple requests at the same time, we need to use threads. Read more.

NodeJs has built-in http modules that allow developers to build web applications without the need to configure and run a proprietary HTTP server such as Apache or Nginx. Other programming languages provide similar libraries that allow developers to bundle a server with an application. So in this article, we'll take a look at how easy it is to write a simple single-threaded HTTP server in Java. Once we're done, we can run a simple test using Apaches ab tool to determine how many requests per second the server can handle. Read more.
