.txt file is attached. I also ran procstat -kk <pid> in a loop for a bit while it was running. In this case the list too just under 5min to run. time /sbin/zfs list -Hp -oname,creation -S creation -t snapshot > /var/log/snapshots.out 2.311u 24.963s 4:55.13 9.2% 71+179k 2706576+26io 0pf+0w Ideally, I would like to bias slightly ARC to hold this meta data a little longer than evict it out of cache so fast. I put in an nvme disk hoping that would help, but it makes no difference or doesnt seem to anyways. ---Mike _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
