The project explores server-side rendering techniques, performance optimization through profiling, memory management, and networking challenges. Key insights include using double buffering, worker pools, bit packing for data compression, and TCP websockets for multi-client synchronization. The final implementation achieves 2.5 million particles at 60fps while supporting 300+ concurrent clients on a modest VPS. ## Full article daily.dev links to this article rather than hosting it.
