Half and half SSD/HDD Raid10 Mirror performance
ZFS only issues parallel reads when scrubbing. In normal read cases, it issues a single read to a leaf device. Assuming you're using OpenZFS, see: https://github.com/openzfs/zfs/blob/master/module/zfs/vdev_mirror.c function vdev_mirror_io_start, lines 671-675: /* * For normal reads just pick one child. */ c = vdev_mirror_child_select(zio); children = (c >= 0);

ZFS is mysteriously eating my CPU
Actual issue here: https://github.com/openzfs/zfs/issues/6531
It seems the whole thing took place in 2017 and was fixed then (first by not calling the reclaim of used ARC memory was zero, then the root cause also fixed by using a PRNG instead of the default CSPRNG in 0.7).
I’m confused, looking at the GitHub ticket - this issue appears to have never been fixed.
You’re right, the hack/workaround to not reclaim ARC if it’s below a size was written but not merged [0]. But the PRNG thing (actual CPU usage bug) is real and in 0.7+ so far as I can tell. Ideally both would have been committed.
