Status Graph double-counting traffic?

[biggsy]

Hi,

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

I recently moved my nas4free install to my ESXi 5.5 Box and I also saw that webui's traffic graphs double counting all incoming traffic. Outgoing traffic is correct. My first guess was ESXi's was duplicating packets because I have NIC failover configured on ESXi. 'netstat -s' has a line for duplicate packets

Code: Select all

tcp:
......
                131097 completely duplicate packets (3182 bytes)
.....
 

3182 byes isn't much. I think it safe to ignore. Both windows 7/8 file transfer speed/task manager and vSphere client report correct network speeds.

I can echo issue of double counted traffic when running under ESXi 5.5 u2 using VMXNET3 and E1000 from a Win8.1 machine.

This is just a home rig for me. So not a show-stopper or anything.

Quick one here please. Does it have any known bugs on certain OS?
