With latest Clonezilla I see a huge performance boost using the now default -a3 option for partclone: 30 GB/min -> 50 GB/min. Thanks for that!

But ntfsclone is still faster with 60GB/min.

Is there a way to use the -a0 (no checksum calculation) option for partclone automatically with ocs_live_run/ocs_live_extra_param? How to provide this option to partclone in grub.cfg?

Currently Im using the below setting. How must this be extended/changed?

ocs_live_run="ocs-sr -c -nogui -srel -p choose -j2 -edio -senc -sfsck -q2 -z9p -sc -scs savedisk autoname nvme0n1" ocs_live_extra_param=""

Thanks in advance!
