iSCSI speed problems

Hi all. I was able to set up an IBM Ultrium LTO 4 tape drive to use iSCSI (using open-iscsi drivers) to communicate with Red Hat, but it's going really slow, maxing out in tar and dd tests at like 16 MB/s (using a block size of 128k). The thing is rated for 30MB/s. I feel like even though I have a Gigabit ethernet setup, its only utilizing 100MBit. I have no idea how to mess with network settings either in Red Hat or open-iscsi. Any ideas on what to do, either network or otherwise?
