Comment (by anonymous):
I am sorry that I dont have an ancount on here, it's hard for you guys to
talk to the real person right, I will see if I can register by time.
Anyway...
1.) Those "doubled pings", latency spiking from 12ms to about 3x ms, are
new since this patch was applied, pings were stable before.
2.) It is just, when there is some decent load on the line, but nothing
near max. I have a 12/1 line, and the spikes begin when I for example open
a twitch.tv stream, which has about 3mbit. I have checked this with bmon
too.
3.) Those ping spikes can be monitored on the device itself (wndr3800),
and behind it, from a pc for example which is connected to the 3800's
switch.
4.) I dont use any QOS on the wndr3800 itself, it is connected via wan to
another OpenWRT router (wbmr-hp-g300h), so double nated.
5.) I am using mangled routing on the wndr too, maybe thats a part of the
problem line. But the CPU of the router never reaches anything critical.
For example I use IPSet DHCP rules to route twitch traffic though my wan
device, because all other traffic is going through an OpenVPN tunnel.
