Verification incredibly slow but backup is fast

Hi, 

I run a backup job that is about ~7TB, the backup job runs fast and even reaches over a gbps at times but when I run the verification it is painfully slow and stays at 16mbps :\ terrible. I have tried restarting the server/device. I have tried changing the settings to run the verification on the client and I still get the same. Running a verify job at 16mbps on 7TB of data is painful. 

Any ideas? Anyone had this before? 

Thanks a mil.
