opendedupe configuration dont help increase performance

backupexec 21 with opendedup running very low compare to directly to cloud, 

backup direct to cloud about 4.000+ MB /minute compare to backup to opendedup with cloud volumes only 400MB / minutes. that running in the same time in the same BE Server and same source from vcenter
 
environment:
Backupexec 21.2 rev1200
Running on hyperv on windows server 2016 with latest update
SDFS-3.6.0.13
Disk 2Tb (using ssd 512gb x 4, raid 0)
Local Cache using 1Tb
Backup to GCP standard storage
CMS Server: 16 core, 40GB Memory
BE 2-4: 8 core, 25GB memory
 
disk io should be fast enough,
is there any configuration can be tuning to increase performance job rate?
 
volume created with OST plugin:

dont help any increase performance
upgrading to BE 21.3 hope if there enable cloud dedupe, but it applied only for gold or silver licenses, current licenses we are using is vray edition
 
any suggestion or experience performance problem using opendedupe backup to cloud
 
 
  • You can try the backup to Deduplication enabled cloud storage with v-ray edition.
    Create a deduplication storage first and then enable deduplication feature checkbox while configuring the cloud storage
