When I extract a large tar file , like
I've been fighting this issue for a while, but it never reached a high priority for me until recently. I want to say it's been happening since 11.1, but I do not have any data to back that up. I have FreeBSD 12.1 installed on a pair of Western Digital WD500AAKS drives using a 120Gb UFS gmirror (balanced round-robin), remainder of drives are configured for ZFS (mirrored pool). System is i5-7500 w/32Gb ram, ASRock Z270 mainboard. I have a couple of other systems configured about the same (mix of UFS gmirror and ZFS) and see the same issue.
I realize the above is not a lot of info, just trying to figure out where to start troubleshooting. The only disk tuning I have set in either /boot/loader.conf or /etc/sysctl.conf is just a single ZFS entry limiting ARC usage. Smart is enabled and has not logged any errors. This may be just an issue with cheap drives paired with cheaper onboard SATA controller, but I wouldn't think the system would be in such an unusable state doing a single tar extraction.
tar -xf /usr/ports/distfiles/firefox-76.0.1.source.tar.gz
, the process just grinds the whole system to a crawl. Overall system latency returns to normal after extraction is complete.
