Hi
I've been reading a lot on 10Gbe, but the amount of details is a bit overwhelming.
Hoping for someone to point me in the right direction.
I have a x9 dual xeon 192GB supermicro box with a 2-vdev pool both 10 wide z3 w 3TB enterprise disks.
Direct attach to my main win10 workstation. Both boxes with Intel X540-T2 cards
I have done no tuning what so ever. Simple SMB share. I've transferred 15TB of data from the workstation -> freenas with a pretty constant transfer rate of about 300MB/s.
As part of a backup job I then needed to transfer the same mixed file set the other way, but the transfer speed is regularly changing in a constant pattern, attached. It's going back to the same raided disk config on the workstation (4 12TBs in software RAID10)
I was hoping someone instantly recognised this speed graph as a symptom of something I can read up on and fix, maybe with some tunables?
Any help appreciated.
