I do not know any open source implementation of an efficient LPM. FYI,
some data with a commercial one:
-> up to 160Mpps, the bottleneck was the IOs, not the CPU.

Hello,
We are trying to benchmark L3FWD application and have a question regarding
the IP lookup algorithm as we expect the bottleneck to be at the lookup.
Could someone let us know how efficient the lookup algorithm that L3FWD is
using (e.g, LPM)? We are asking because we want to obtain highest L3
