pub static RDMA_CQ_BUSY_POLL_WINDOW: Key<Option<Duration>>Expand description
Cooperative-yield window for the ibverbs CQ poll loop. While
the policy is within this window it calls
tokio::task::yield_now between polls; past it, polls fall
into an exponential backoff sleep (1ms initial, x2, capped at
10ms). None (the default) disables the cutoff entirely:
the loop only ever yields, never sleeps.
