Slow write performance 4324G2

Was googling and looks like other folks have had the same complaint. We purchased a D2D4324 G2 with 2nd drive shelf. Currently using it with EMC Networker. Networker also has a MSL 6060 (LTO3) and MSL 4048 (LTO4) attached to it over 4GB FC. Writing to those libraries over FC is anywhere from 90-130MB/min.Wrting to the VTL the most I ever see is 40-50MB and takes 2-3 days to backup a few TB of files off a linux host. 


I have the VTL emulating a ESL LTO 5 library with 5 drives and 64 slots (no particilar reason just chose to have it emulate a non MSL series library so to not get confused with the physical libraries. The 1G interfaces are connected as Active/Passive. 


Can someone help point me in the right direction?

Please review the attached document. It has some Networker specific information in it. Don't know where on hp.com this has been hidden, so I attached it to this post. Let me know if this helps to speed up things for you.
