Fsautility take a long time to run

Hello,

I have a customer  that want to move  placeholder from one location to another location on same File server.

I run the the FSAUTILITY  but it`s take a long of time

 FSAUtility.exe -pm -cs -s <source UNC> -d <destination UNC>.

we test  the fsautiliy to  200 files and it`s take ~30Ssec

it`s mean that if I want to move 2.930,117 Million files (314Giga) it will be finish after 5 days.

how can I improve the perfomance ?

Thanks Ronen
