I had noticed this some time ago but forgot to ask about it in the forums.
I believe that the traffic graph is double-counting traffic on my system. I'm running 9.1.0.1 (847) 64-bit in a VM under ESXi. The vNIC is configured as vmxnet3 but I've tried e1000 as well.
While ESXi, Task Manager (networking) and Windows Explorer all report transfer speeds of around 60 MB/s, the NAS4 Free Status Graph shows about double that (~120 MB/s). I've seen this quite consistently in the past week or so.
Anyone else see this, under ESXi or otherwise?
Thanks
EDIT: Also tried systat -ifstat 1 which showed similar numbers. However, I think a peak of 234 MB/s is probably unrealistic for a gigabit ethernet connection
