Accessing files over the wire is always going to be slower than if you access a local disk. You might be able to increase the performance of the scan if you set it up to run the scan locally. Whenever you start pulling files across the wire you will start noticing these types of slowdowns due to the number of files being accessed.
If you run the same scan remotely it will have to setup the connection to transfer/access each file which is why it is probably so slow.
It is possible to tweak the protocol you are using to access the files, but you will see much more dramatic results just moving the process to a local scan versus a network scan.
Something to note here, many enterprise class backup solutions also include a locally installed component that serves this very same purpose. The files can be transferred in a push versus a pull across the network which is a significant improvement.
