Bad performance on EMC VNX after upgrade to 7.5.0.1

Hi!
After upgrade of Master Server to 7.5.0.1 and NBU 5220 Appliance (Media Server) to 2.5 our NDMP backup to MSDP has decreased from around 60-70 MB/s to now it's 360 kB/s.

Haven't changed anything in policy selections are:

set TYPE=tar
/root_vdm_2/fs1

Don't get any error but just bad performance

Do I need to change selections or anything else?

Since 7.5 NBU uses new Streamer for EMC NDMP to be able to do a better dedup.

This needs a new FULL backup to seed new MetaData so the answer is do a FULL backup of the EMC NAS after upgrade to 7.5.x.x
