Hello guys,
Thanks for suggestions.
Tweacking sysctl
net.inet.udp.recvspace=131072
net.inet.udp.sendspace=131072
solved the problem.
Test between routers that started to drop packets over 10Mbit, now run
test at 100Mbit with less than 1% drops (over 50% before).
net.inet.udp.recvspace and net.inet.udp.sendspace only affect traffic
generated on a machine itself, they do not affect forwarded traffic.
Generating packets on the router itself isn't a good test for how well
they can forward packets.
Hi Stuart,
I have read it many times that increasing the values do not affect
forwarding performance. That is is why I was skeptical about calomel.org
solution.
Can you point some directions for increasing forwarding performance?
I upgraded all routers to 6.7 with patches and I think problem
disappears, using the same hardware.
Thanks for your help,
Ivo
