Using a single path (without MPIO) as a baseline:
With bonding I saw, on average 99-100% of the speed (worst case 78%)
of a single path.
With MPIO (2 nics) I saw, on average 82% of the speed (worst case 66%)
of the single path.
With MPIO with one nic (ifconfig downed the second), I saw, on

If you have just a single iscsi connection/login from the initiator to the
target, then you'll have only one tcp connection, and that means bonding
won't help you at all - you'll be only able to utilize one link of the
bond.
Note, the EMC specific bits of that multipath.conf were just copied
from boxes that use FC to the SAN, and use MPIO successfully.

Hi Kyle.
For your configuration do you have a LUN in the storage group
assigned to your server? If so, the LUN is presented to both SPs
(service processors) but only owned by one. If your storage group for
the server has been configured for the default mode the LUN is presented
in PNR
