Their post isn't really about bloat. It's about the discrepancy in i/o 
bw of memory off-chip and on-chip.

My opinion is that the off-chip memory or hybrid approach is a design 
flaw for a serious router mfg. The flaw is thinking the links' rates and 
the chip memory i/o rates aren't connected when obviously they are. Just 
go fast as possible and let some other device buffer, e.g. the end host 
or the server in the cloud.
