I run a ESXi 6.0 setup on a Supermicro A1SRi-2758F using a USB key to boot ESXi from, a 240GB SSD as a datastore, and a 480GB SSD as a RDM on the Datastore for a specific VM.
I notice that when I copy something from within the VM with has the RDM drive mounted (FreeBSD installation) to my NAS, I get a maximum of 43MByte/s throughput.
When I copy something from my desktop to the NAS I reach 100 to 105 MByte/s.
Both the ESXi and the desktop are connected to the same switch.
I have a vSwitch with two NICs for VM LAN usage (got a seperate just for management) and I already tried removing one NIC, and setting the physicial switch ports to normal.
Meaning no LACP or Static port channel. Can't get that to work properly anyway.
Since I can't copy directly to the RDM drive, I copied something to the Datastore from my desktop. I get a max of 70MByte/s there using the same file from the same hard drive as I copy to the NAS.
What could I be missing here? Why is my performance so low?
