HyperV and Networker 8 slow Rate

Question

Hi, I have a cluster of 3 Nodes Hyper-V 2008  with backups of Networker latest updated edition. When i run a backup job with 30 Clients it loads 10 session to 2 Tapes with a rate of 80-90 MBs which is good if the Backup server has only 1GB lan . The problem is if suppose 5 session are finished and only 5 left (although in queue are more still) the rate of 80MBs go to something like half ,and if i do a test Job  of only 1 VM to backup its rate is somthing like 25MB so what am i missing,is there something on  HyperV or Networker Server i can check?

Do you use switched network?  In switched network usually (over 1Gbps) sessions won't run over 25-35Mb/s.

Yes its switched over 1GB.But NDMP Runs faster.Physical Server runs FasterHyperV Hosts runn slow.

In that case it might really be that hypervisor has issue pushing data out.  Independent way to see that is to emulate same conditions outside NW - but for that you will need assistance of MS so having a call with them is a good thing.
