I would like to understand why I need about 13 h to copy a folder from my local /home path to another local disk. This folder has 128 MB.
The only thing I think is different here is because I am copying from BTRFS file system to NTFs file system.
cp -r atividades_Impacta/ /mnt/sdb1/__Impacta/atividades_impacta

What happens if you copy the folder to /dev/shm and from there to the ntfs drive?
It goes normal to there. Very fast indeed.
My fstab:
UUID=8bf37574-0440-456c-9889-ddc095a32fc7 /home btrfs subvol=home,compress=zstd:1 0 0
#Documentos
UUID=0E6A5F856A5F688B /mnt/sdb1 ntfs-3g defaults,users,auto,sync,rw,umask=000 0 0
I check here better. If I try to copy anything to this mounted drive it took many many time to complete operation
I found the problem!
You must not use “sync” option! This option drags your performance down.
