Overview
A Java multithreaded TCP server built from scratch that can handle 1 million concurrent client requests using thread pools. This project showcases advanced system design principles, efficient resource management, and high-performance networking in Java.
What It Can Do
- Handle 1M+ concurrent connections: Scale to massive client loads with proper thread pool sizing
- Uses ExecutorService for thread management: Implement efficient task scheduling and resource allocation
- Optimized socket I/O operations: Minimize latency and maximize throughput with non-blocking I/O patterns
- Built with raw Java sockets: Deep understanding of network programming without framework abstractions
Why I Built This
To learn about system design, concurrency, and network programming at scale. This project explores the challenges of building distributed systems that can handle real-world traffic patterns and maintain stability under load.
