I'm facing a weird problem with the Realtime Traffic Graph in OpenWrt.
So basicaly since I've started with OpenWrt on my WRT3200ACM I observed that the Traffic Graph in for my pppoe-wan interface (Realtime Graphs >> Traffic >> pppoe-wan) does report wrong current and peak traffic rates (down + upload). If I remeber correctly this was the case from the beginning on an I was never able to figure out the cause of this. I also never saw any reports about it in the forum so my tought was that it must be related to my setup/configuration.
For example my current availible download speed based on the calculation from the syncrate of my downstream (@pppoe + vlan tag +MTU 1492) would be ~108mbps which I limited via SQM to 102150kbps but when doing speedtests or maxing out my download speed in any other form I do see peak rates of 150+mbps at the traffic graph of the pppoe-wan interface.
The same goes for my upload speed which based on my Upstream syncrate would max out at ~34.6mbps but the traffic graph reports a peak rate of 45+mbps which seems to be quite unrealistic.
Without SQM I do see even higher peak rates.
Setup: Bridged VDSL modem >> WRT3200ACM@OpenWRT@pppoe (davidc502 build)
Speedtest@SQM directly on my router:

Does anyone have a clue on what could be the cause of this issue and how to fix it?
