and flamegraph while it is idle: http://www.lundman.net/zfsboot.svg `arc_reclaim_thread()` shows a bit too much, I would expect that to be mostly idle (even if low on memory) `zfs_vnop_pagein()` also taking a...

`arc_reclaim_thread()` seems to be looping here: ``` } else if (evicted >= SPA_MAXBLOCKSIZE * ARCSTAT(arc_reclaim_waiters_count)) { // we evicted plenty of buffers, so let's wake up // all the waiters...

Just pulling out the zfs calls, and sorting on frequency: ``` 31 lz4_decompress_zfs 31 zap_lockdir 32 dmu_read_uio_dnode 35 dmu_buf_hold 35 zfs_vnop_read 36 zfs_read 43 - 48 zio_done 55 __zio_execute 61...

Note to self, ``` module/zfs/spa_config.c spa_write_cachefile() ``` will panic during boot, due to `vn_open()` being called before `rootvnode` has been set.

Ok, the boot issues have been fixed, except for the performance one. There is a signed PKG on wiki if anyone wants to try ZFS on Boot.

You can `sudo reboot -qn` though, but only after `sync`ing first as it is a dirty reboot. It sounds like your disk gets disconnected, and if it disappears from DiskUtil...

I'm actually surprised that freebsd will import file-based pools at all, didn't think any platform did. You will have to add a line to the the zpool-import script to add...

It's not the first time either, when we sync from upstream they can be lost. I wonder if perhaps we should do a zfs_osx.8m as well, so we can stay...

That looks more like the findericon problem, mentioned here: https://openzfsonosx.org/forum/viewtopic.php?f=26&t=3299&start=10#p9645 You could test it by creating a ".VolumeIcon.icns" *directory* on the Linux side, so it already exists when you send...

Ok so you confirm the VolumeIcon is also an issue for you. Then separately, there is an issue using Finder to descend into directories more than one deep? What are...
