This limits confirmation.) Note to avoid misinterpretation: I am in general agreement with the following as appropriate experiments . . . "You need to add non-flash swap" and "Spinning disks suffer much less from these issues" although I would explicitly add that there are SSD-based USB drives and at least some of these might be about as good as using a direct SATA SSD environment with good SSDs. (Correct me if I'm wrong for some reason.) Notes on testing: Having records from, say, periodic gstat runs, is a good cross check in all cases. Having the information-reporting patches from Mark Johnston are appropriate for testing as well. http://www.zefox.net/~fbsd/rpi3/swaptests/tools/ has various things that have been used in testing. But batchqueue.patch did not pan out and likely should be avoided. Similarly for config_options. The readme is what talks about: sysctl vm.pageout_oom_seq=3D120 The rest are patches for reporting of additional information during operation. These are likely more important than the gstat ms/w and ms/r records. The context for the patches is recent head, not 11.x . --=20 You are receiving this mail because: You are on the CC list for the bug.=
