slow ntfs restore

Hi All

I created a compressed fsa archive of following data

NTFS Filesystem
Data Size is 5227MB


using the below command

fsarchiver savefs --compress=1 /mnt/bkp/myarchive.fsa /dev/sda2

it took 6 minutes and 32 secs to create the backup and image size is 2.6G, excellent.

and then restore the fsa archive using the following command

fsarchiver restfs /mnt/bkp/myarchive.fsa id=0,dest=/dev/sda2

and it took 17 minutes to restore.

Can anyone kindly explain why it is too slow during restore?

Regards,

was it to a HDD, or SSD?
Using an SSD I found using the default kernel from SRCD without the trim command was slower to restore a backup. Once booted into windows and the SSD was cleaned after the use of a non-trim aware OS, the next restore using the alt-kernel (newer w/trim support) from SRCD was much quicker.

The backup image was created on external USB HDD and restored on internal HDD.
