Slow Backup Performance

We are currently testing various backup product for long term retention of data. The performance we are getting is extremely slow from VM's on ESX 5.1 and backed by a CS460G. The 2 ESXi 5.1 Hosts have 14 VM's (7 each) and these are just idle as switched on but doing nothing, the Hosts have 2 1GB iSCSI connected NICs. Similar tests on the old ESX infrastructure (Production) backed by NETAPP FAS 3120 are 2-3 faster. The NetApp and hosts are connected by fabric (FC) HBA's and perhaps it's an unfair comparison. However we not getting it 1GB speed. Theoretical max of 125MB's but I'd be happy with 50-60 MB's. Any suggestions?
