Backup Exec 15 Slow Verify

Our Backup Exec is using an AWS VTL and can back our data up in a reasonable amount of time but the verifys are extremely slow. Right now we have a job that ran around 1700 MB/min and is verifying at 223 MB/min. We've setup antivirus exclusions and upgraded Backup Exec to feature pack 1. The Backup Exec server is a Windows 2012 R2 box. I'm not clear on what else we can do to speed this up so any assistance would be greatly appreciated, thank you.
