Upload Bandwidth Throttle

Hello and thank you for taking the time to read my post.  I've recently installed Norton Zone on my Windows 8 desktop.  I decided I should backup my iTunes library.  This totaled about 16gb in size.  When Norton Zone begins to synchronize the folder, it takes 100% of my available bandwidth.  Any device on my network is unable to access the internet until the synchronization is complete.  Pausing the synchronization alleviates the problem.

 

Is this normal?  If so, are there any plans to add a throttle setting to the product?
