Digging into forwarding latency, there are a few things
1. Seems to be caused due to forwarding packets queued before bind. They
would be in the queue till bind. There are two ways it is showing up
a. Bind itself is delayed and releasing queued packets causes the
high forwarding latency.
b. There is a significant gap between bind and first packet being
pulled off the queue to be forwarded, in one example 100ms.
(a) is understandable if the signalling delays things. Can drop these
packets without forwarding or indicate in the packet that it is a queued
packet and drop it from forwarding latency calculation. Dropping is
probably better as down stream components like egress will see a burst
in these situations.
(b) looks like go scheduling latency? Unsure.
Logging more to understand this better.
