Hello,
Here are the test results from my testing of the latest patches of btrfs
dedup.
TLDR;
I rsynced 10 separate copies of a 3.8GB folder with 138 RAW photographs
(23-36MiB) on a btrfs volume with dedup enabled.
On the first try, the copy was very slow, and a sync after that took
over 10

Hi Liu,
Thanks for your work.
Each test copy 2gb file from sdf (btrfs) to sde (btrfs with dedup 4k
blocksize).
Before every test i recreate filesystem.
On second write all goods.
Test 1
Nodesize = leafsize = 4k
Write overhead ~ x1.5
Test 2
Nodesize = leafsize = 16k
Write overhead ~ x19
