To enable, set to true. The sentinel-based rate limiter provides a smoother performance curve as rate-limit calculations happen off-thread, but a stricter time-out based cool-down for clients, i.e. when a throttling action is triggered, they are required to cool-down for the period of the rate limit.

Disabling the sentinel based limiter will make rate-limit calculations happen on-thread and therefore offers staggered cool-down and a smoother rate-limit experience for the client. I.e. the client can slow their connection throughput to regain entry into their rate limit, this is more of a “throttle” than a “block”. The standard rate limiter offers similar performance as the sentinel-based limiter. This is disabled by default.
