I just realized that the older thread got a bit confusing, so I'll keep
problems separate and make things simpler :)
On an _unencrypted_ partition on the SSD, running du -sh on a directory
with 15K files, takes 23 seconds on unencrypted SSD and 4 secs on
encrypted spinning drive, both with a
Hi Alexander,
I did some testing of the case where same inode, but with a different
generation, exists both in send_root and in parent_root.
I know that this can happen primarily when inode_cache option is
enabled. So first I just tested some differential sends, where parent
and root are unrelated
Hi Arne,

SSD's do not gain anything by having metadata DUP turned on. The underlying

blocks into the same erase block which effectively eliminates the benefit of
duplicating the metadata on disk. So detect if we are formatting a
