This sets how many circuits are evaluated for load balancing within each circuitLoadBalanceInterval period, capped at a maximum of 10 circuits per second by the platform. Raising this value speeds up how quickly a large batch of circuits gets rebalanced onto better ring paths after a network change, but doing many rebalances per second risks more simultaneous traffic disruption since each moved circuit briefly interrupts its own traffic. For example, on a device carrying hundreds of circuits, setting this near the maximum of 10 would clear a rebalancing backlog far faster than the default of examining just one circuit per interval, at the cost of more concurrent switch-related traffic hits.
