You have to consider tape seek, rewind time and so on.. It's the same in Netbackup, it will jump from 2MB/s to 50MB/s and so on.. Restores are always slower than the actual backups.
To find your bottleneck though, you'd have to perform individual tests. Test by doing it on this host and possibly on another test host with and without the bonding, etc. And again, never judge your speed by the backup software as most can use cache compared to what is actually being written to disk, etc.
