Depends on many factors. If you use gzip compression (tar.gz) also your cpu is a limiting factor (only one cpu is used here). Check your processes during the backup process. With 2.0 rc1, we introduced lzo compression, much faster and the default now.
If you store your backups on a NAS, obviously also the network has impact.

For most it makes no sense to put all resources of the host and network to speed up backups. Much more important is a low load during backups in order that all VM´s are working well during backups.
