EV 10 sp1 FSA With Celerra restore/copy performance

hi,

We installed enetrprise vault 10 to archive Celerra
and it`s take a long time to copy or recall a file
for example:
10 Mega Mpeg file =~2 min
100 mega AVI file =~10 Min

also you can see the dhsm connection

fs_dhsm connection:
ev-test:
state                = enabled
offline attr         = on
popup timeout        = 0
backup               = passthrough
read policy override = full
log file             = on
max log size         = 10MB
cid                 = 0
   type                 = HTTP
   secondary            = http://ev-test.domain.com/EnterpriseVault
   state                = enabled
   read policy override = full
   write policy         = full
   user                 = evadmin@domain.com
   options              = cgi=n

please advice me
