SCHEDULING INTERNALS

Summary from the TLDR Web Dev newsletter

This post dives into the internals of scheduling and concurrency, showing readers how to handle millions of clients concurrently with just a single thread. It begins by exploring the challenges of creating a server that can handle multiple clients concurrently using threads, going over concepts like stack allocation, performance, and resource management. It then introduces the concept of async I/O, demonstrating how non-blocking sockets can be utilized to achieve concurrency without threads. Code examples are provided to demonstrate the points made.
