Robocopy making disk access very slow

Question

Hello ,

I am using Robocopy to periodically copy data media data (mp4 video files) from Local drive to network drive.

When Robocopy is executing copy command, local disk access is very slow and becoming almost unusable to open it.

Tried with different thread options 8,16,32 etc. but disk performance issue is not solved.

Any reason why robocopy is hampering local disk performance so badly.?

Thanks

I would expect that there would be sufficient network delay to prevent an overload of the local disk.

Try adjusting the IORate switch to suit your needs.
