ThreadWave🌊 (Built with Java)

This repository showcases various implementations of Java web servers using different concurrency models: Single-Threaded, Multi-Threaded, and ThreadPool. These web servers are developed using Java's ServerSocket and Socket classes to handle client requests, and their performance is rigorously tested using Apache JMeter under various load conditions.

💡 Note: Each web server model in this repository has been thoroughly tested by generating 600,000 requests. This extensive testing highlights the robustness and efficiency of each model under significant load.

Single-Threaded Web Server

Description

This is a basic web server implementation that handles one client at a time. It utilizes a single thread to manage each client request sequentially.

Cons:

• Limited to handling one request at a time, which can lead to slow response times under heavy load.
• Not suitable for high traffic scenarios due to its sequential nature.

Performance:

• Performance testing with Apache JMeter indicates limitations under heavy load. Here’s a graph depicting the results:

Multi-Threaded Web Server

Description

This implementation enhances concurrency by creating a new thread for each client request, allowing multiple clients to be served simultaneously.

Cons:

• High memory usage due to the creation of a new thread for each client request.
• Potential performance degradation if the number of threads grows too large.

Performance:

• Performance testing with Apache JMeter shows improved concurrency but with increased resource usage. Here’s a graph illustrating the results:

ThreadPool Web Server

Description

This advanced implementation uses a fixed-size thread pool to manage client requests. The thread pool consists of a predetermined number of threads, efficiently handling client requests by reusing threads.

Performance:

• Performance testing with Apache JMeter demonstrates excellent scalability and resource management. Here’s a graph showing the results:
