| H A D | napi.rst | 16 interrupts first (:ref:`busy polling<poll>`).
255 Busy polling
258 Busy polling allows a user process to check for incoming packets before
259 the device interrupt fires. As is the case with any busy polling it trades
260 off CPU cycles for lower latency (production uses of NAPI busy polling
263 Busy polling is enabled by either setting ``SO_BUSY_POLL`` on
265 ``net.core.busy_read`` sysctls. An io_uring API for NAPI busy polling
266 also exists. Threaded polling of NAPI also has a mode to busy poll for
267 packets (:ref:`threaded busy polling<threaded_busy_poll>`) using the NAPI
