Some Trie Operation Benchmarks

Specs: go 1.19.2 on a MacBook Pro MacOS Ventura 13.5.1 with the Apple M1 Max processor and 32 GB of RAM goos: darwin goarch: arm64

Of course, the benchmark numbers depend on the subnets in the trie and the address used to search. In general they show that operations are on the order of hundreds of nanoseconds. In particular, subnet containment operations are very fast.
