I pause for 120 seconds, then initia= te a manual trim zpool trim -w pool and then pause 120secs and then start again.= As you can see the throughput is consistent on writes. Then at 08:00 I restart the test, but this time I dont do a trim after the zfs destroy. If manages about 3 times (the dataset is about a 1/3rd of the pool's capacity and then= the writes become brutally slow which tracks FreeBSD. If I then do a zpool tri= m -w pool, performance is back to normal. --=20 You are receiving this mail because: You are the assignee for the bug.=
