## Queueing Theory

Queueing theory is the mathematical study of waiting lines or queues, used in finance to model and optimize the performance of trading systems and matching engines. It helps architects understand how order arrival rates, processing times, and system capacity interact to create bottlenecks and latency.

By applying queueing models, engineers can predict how an exchange will behave under high load and design systems that maintain stability even during market surges. In derivatives markets, where speed is paramount, minimizing the time an order spends in a queue is essential for execution quality.

This theory is also used to analyze the impact of network congestion on blockchain transactions, helping developers understand how to prioritize and schedule tasks effectively. It provides the rigorous framework needed to balance system complexity with performance requirements.

Understanding the flow of orders through a system is vital for building robust financial infrastructure that can handle the demands of modern global markets.
