hi,

so as noted yesterday, i got my 10gbps nics finally so i had a quick
experiment in my homenet.
initially i hooked the traffic up with my stordis but after the 2nd copy of
my rib+fib it given
up and made a permanent forwarding loop so i removed that guy and continued
with a direct loop...
the idea is that i used point2point vlans where i enabled my igp in different
vrfs on the ends and this made up a chain:
sdn6.101--sdn7.101--sdn7.102---sdn6.102.....
my rib have 250 entries (per vrf) that is 2.5k but my fib uses sr with block
size 300
so i ended up with an 3.7k fib programmed in total...

the forwarding was done by a 7 years old i7-3770 over intel nics.
finally i reached a constant 6+6=12gbps rate with 30% load of 2
threads dealing with the 2 tengig ports, and a 9% cpu for the gig
port's thread... those tengig ports are unfortunately bound to the
threads of the same core so it could be better, moreover if i had
more cores then i would bound rx and tx workers to different cores...
finally i given up the vrf/subif/igp creation, we can estimate
from these numbers enough: one thread forwards 6gbps with 30% load,
so one thread could do 18gbps with 90% load.... and as noted above,
we can split rx and tx so it's quite inspiring!!!!

afterwards, i've enabled macsec on each subifs... at this time
i as able to maintain 1.2gbps flow / port so i had a 2.4gbps total
crypto throughput with 2 threads maxed out at 100%, but that cpu
have 4 cores (8 threads0 so that cpu is capable of 9.6gbps total
crypto throughput. i used aes256+sha1 in this experiment.

regards,
cs
