I run it daily during the week, at a time when load is practically nil, on 
two boxes with 24TB storage each, divided into six parts of about 4GB. A 
10-pass xfs_fsr run usually completes in under one hour, except on monday, 
when it takes three to four hours.

I don't have any stats on the net effect, though.

Regards,

roel
