Response times of what, to what?  IMNSHO, this is going to be pretty =20
difficult sticking with linux, because linux is not a "real time =20
operating system", and guaranteeing <10ms behavior is getting into the =20
realm of things where you might need some of those "real time" features.

PPC, MIPS, and ARM are all pretty equivalent.  I think PPC and MIPS =20
may have a head start in "router-like-box" department; more chips with =20
multiple ethernet MACs compared with ARM.

Consumer routers are almost all based on chip vendor reference designs =20
and would probably make a good starting platform for experimentation =20
and performance measurement, as appropriate.  The ddtwrt and/or =20
openwrt list of supported hardware should give you a lot of info on =20
what chips are out there...
