Queue Capacity

Definition ∞ Queue Capacity refers to the maximum number of items or operations that a waiting line within a system can accommodate at any given moment. It defines the limit of pending tasks that the system can hold before new items are rejected or delayed indefinitely. This parameter directly influences system throughput and latency.
Context ∞ In blockchain networks, queue capacity is a critical factor, particularly concerning transaction mempools, where unconfirmed transactions await processing. A limited queue capacity can lead to network congestion during periods of high demand, resulting in increased transaction fees and slower confirmation times. Optimizing this capacity is a key consideration for improving network scalability and user experience.
