Benchmarking
Litecoin Core has an internal benchmarking framework, with benchmarks for cryptographic algorithms (e.g. SHA1, SHA256, SHA512, RIPEMD160), as well as the rolling bloom filter.
Running
After compiling Litecoin-core, the benchmarks can be run with:
src/bench/bench_Litecoin
The output will look similar to:
# Benchmark, evals, iterations, total, min, max, median
