Hello,
I've noticed that running "du -sch" on a btrfs takes much longer that
it on ext4 filesystem have the exact same copy of data ...
Also, running "find -type f" for example is much slower on btrfs that ext4 ...
I could reproduce this on;
1- a single 64GB Intel X-25E SSD
2- and on a 6 x 1TB SATA II disks on RAID-0
Notes:
1- Both filesystems have been recently populated with the same copy of data
2- I'm using -o compress for btrfs
Thanks
