Worker Thread-Based HTTP Server

Harper 4.1 introduces a shift from using processes to worker threads for handling HTTP requests, enhancing concurrency and resource utilization. This change allows for better traffic control, session affinity, and debuggability, while also supporting alternative storage models. Worker threads, requiring fewer resources than processes, enable efficient use of memory by sharing a central pool for asynchronous tasks, contrasting with the high overhead of maintaining multiple processes. The main thread in Harper listens to a network port and delegates connections to worker threads, which handle HTTP parsing and response tasks, a method particularly efficient on Unix-based systems but less so on Windows. The approach leverages modern CPU capabilities for parallelism and is applicable to various JavaScript HTTP servers, offering improved performance and control over traditional process clustering methods.
