@puma2009 - which PF\_RING version are you using? There was an issue around [poll/epoll](https://community.zeek.org/t/performance-issues-after-upgrade-to-zeek-6/7094/7) reported ~2.5years ago when upgrading to Zeek 6.0 that we [reported to PF\_RING](https://github.com/ntop/PF_RING/issues/878). It was with PF\_RING 8.2.0 and the [fix made it into PF\_RING 8.8.0 or later](https://github.com/ntop/PF_RING/commit/826cf3768b079bf8ad0837543d290dd39d889859).

Alternatively, a fix in Zeek would be to try and put the following into local.zeek to poll PF\_RING more often:

```auto
# local.zeek - Use more aggressive polling to avoid polling issue with kqueue and PF_RING < 8.8.0.
redef io_poll_interval_live = 100;

```

So if you don’t yet have PF\_RING 8.8.0 or later, try upgrading or see if the above redef helps.

Please report back if any of these steps helps.
