hi,
that looks very interesting, thanks!
bookmarked to test later.

in particular, the performance statistics are impressive, and what has 
my interest.  i have two questions :-)
* is that a sample rate of 1 in 20,000 packets/frames (which is what i 
am guessing) or a ipfix/sflow export rate of 20,000 pps?
* what was your exported ipfix/sflow pps rate for the testing that you 
did  (assuming a 1/20,000 sample size, on iMix traffic)?

i ask because my particular interest is testing this, for sflow exports 
from an ixp that’s in the 100gb/s mark, and i’m being lazy and 
hoping that i can extrapolate numbers for scaling hardware, from your 
testing. :-)
(also the documentation that i read quickly, mentions scaling this in 
pps received)

thanks in advance,
—n.
