Yes, probably you're right as the modification date points to the time
period when I turned on the LAGG

As I understand, on 10.x it's fixed and having more queues results in
better performance?

As far as I will have faster transfer between storage1 and storage2, I'd
plan to upgrade 9.x to 10.x

Cheers,
