real hardware router VS linux router

In scaling upward. How would a linux router even if a kernel guru were to tweak and compile an optimized build, compare to a 7600/RSP720CXL or a Juniper PIC in ASIC? At some point packets/sec becomes a limitation I would think.

While you could probably build a linux router that is just as fast as a
real hardware router, you're always going to run into the moving pieces
part of the equation.

In almost all scenarios, moving parts are more prone to failure than
non-moving parts.

Regardless of what you find out in your research, consider the above in
your cost-benefit analysis.
