Replying to [comment:97 anonymous]:
Are the dropped/overrun numbers constantly increasing? Is the CPU maxed?
txqueuelen shouldn't matter as long as you're not getting TX overruns.
Check eth0/eth1 TX ringsize though (ethtool -g) and make sure they're not
too small. Default is 192. Anything 6 or less is likely to cause hangs. If
you want to lower it, take whatever number you used to have and triple it,
since each full size packet takes up 3 descriptors now. I can re-pro ping
spikes with activity with TX ring size of 8, but not with the default. If
you're double-NATing, do the ping spikes happen when you ping your second
router?
I noticed that sometimes my WAN/eth1 port won't come up or will come up as
10/half, even before this change - usually fixes itself if I reset the
port or replug the cable. TBH it just never bothered me enough to get
around to filing a ticket for it...
