Hyper-V Guest Performance

-

we purchased iscsi san dell house both our vm's , file server storage.  currently our vm's reside on local storage.  i have loaded vm on new storage test performance , basic management operations seem take longer normal.  the first thing noticed loading server manager upon logon seems take longer used on other servers.  i "waiting snap-ins load" while browsing different roles.  this first indication.  (is a legitimate concern?)

additionally, file server performance seems lacking , average read , write speeds around 45-50mb/s seem me low.  

the new storage got md3200i configured 6x15k 600gb sas , 6x7.2k 2tb nearline sas drives.  the vms going on 15k , file server data on 7.2k.

my biggest concern loading our production vm's onto storage start experiencing performance issues.  what steps should go through verify performance before putting production?

thanks in advance,

i have accepted performance is.
