Benchmarking
Bitcoin Core has an internal benchmarking framework, with benchmarks for cryptographic algorithms (e.g. SHA1, SHA256, SHA512, RIPEMD160, Poly1305, ChaCha20), rolling bloom filter, coins selection, thread queue, wallet balance.
Running
For benchmarks purposes you only need to compile bitcoin_bench. Beware of configuring without --enable-debug as this would impact
benchmarking by unlatching log printers and lock analysis.
make -C src bench_bitcoin
After compiling bitcoin-core, the benchmarks can be run with:
src/bench/bench_bitcoin
The output will look similar to:
# Benchmark, evals, iterations, total, min, max, median
AssembleBlock, 5, 700, 1.79954, 0.000510913, 0.000517018, 0.000514497
...
Help
src/bench/bench_bitcoin --help
To print options like scaling factor or per-benchmark filter.
Notes
More benchmarks are needed for, in no particular order:
- Script Validation
- Coins database
- Memory pool
- Cuckoo Cache
- P2P throughput
