Re: [mpls-linux-general] Results with MPLS

[James R. L. <jl...@mi...>]

There has been lots of threads about this on the mailing list.  The short
of it:

- increased latency !=3D slower !=3D less throughput
- make sure you have turned off all debugging (some of it needs to be
  compiled out)
- LERs inherently have a higher latency then normal IP routing (IP lookup
  AND label lookup or push) if you have LERs in your test path, it will
  have higher latency
- mpls-linux is not optimized for speed, but for flexibility and correctness
- I welcome definitive data that proves LSR throughput is sub-optimal
- I welcome patches that provide a definitive decrease in latency or solve
  any sub-optimal throughput if it exists
