I am using Synology DSM 7.1.1-42962 and nakivo10.5.1
When updating to nakivo10.6.1 version, the network speed will become very slow.
After that, I told the original Synology factory to downgrade the version back to nakivo10.5.1,
Internet speed returned to normal.
I don't know if this problem will be improved in version 10.8?
I currently have no plans to upgrade to version 10.7.1.
I will need to upgrade to 10.8 for direct restore from tape.
