next in thread | raw e-mail | index | archive | help
Hi,
I'm seeing loss with polling due to the tunnel driver. Any information
that can help me resolve this will be greatly appreciated.
I'll start with a little bit of background information. This is an IPv6
tunnel server, with 1500 gif interfaces configured. There is also 1
teredo tunnel configured. After upgrading to 7.1 and enabling polling,
The poll loss only shows up when there is tunnel traffic passing through.
If I disable polling, the tunnel driver (used by miredo) starts dropping
packets at a high rate.
There is no packet loss to the machine directly when using interrupts,
but the teredo tunnel introduces loss to traffic being sent through it.
During the test below, there was about 5000pps of tunnel traffic going
to the box. I generated about 65kpps of packets to send to the box, and
you can see the input errors skyrocket. During this test I filtered the
tunnel traffic to the machine, and the input errors disappeared and it
was receiving 67kpps without any issues. As soon as I restored the
traffic, the errors started again.
Does anyone have any input on why tunnel traffic is causing polling
drops? I have modified if.h to change IFQ_MAXLEN to 1000, since 50 was
not enough for the teredo tunnel. The same problem existed before this
change. This has also been tested at 1000hz with no difference. My
settings are below. If I left anything off please let me know.
