How does IE 315 fix sampling issues? You can use 1:1 with or without IE 315? Only thing IE 315 allows you to send sflow style raw frames?
My issue with 1:1 isn't that my platform doesn't support it, it's that it increases backend costs in a way that I cannot justify.
I was focused on the very short attacks. The issue is not sampling, but the flow cache adding some latency, even when tuned down. That's the part IE 315 fixes: there is no cache anymore and the sampled packets are sent directly.
