I’ve noticed this myself but didn’t dig into the delays I’ve seen. Interesting to learn it appears for others.
How did you have ZFS change how it allocates memory?
- allanjude 4y agoThis was a bug in ZFS itself, and was resolved years ago: https://smartos.org/bugview/OS-6404 https://smartos.org/bugview/OS-6404 In FreeBSD 12.x and older, you could opt out of using UMA with: vfs.zfs.zio.use_uma=0, but that is not necessary
- eatbitseveryday 4y agoThanks. I still see multi-second pauses moving data over Samba to an encrypted ZFS pool. I’m using a 10Gbps network card, so the drives are the bottleneck (or so I thought, until seeing these delays). I’m on 13-RELEASE.
