Hi,

Well, different criteria for "inferior", I'd say.  A general purpose
CPU won't be able to feed something with 24x 100Gbit - and a switch
network processor won't be good for running a database...

For queueing/shaping, the network chips have become surprisingly good -
not sure about libreqos & friends, but "doing proper shaping to sub-
linerate to avoid policing drops in a carrier network further downstream"
was something switches just couldn't do, and recent gear (Jericho 2+)
does this quite well.  With proper burst size configured, no bufferbloat
there either :)
