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.
For benchmarking, you only need to compile bench_bitcoin. The bench runner
warns if you configure with -DCMAKE_BUILD_TYPE=Debug, but consider if building without
it will impact the benchmark(s) you are interested in by unlatching log printers
and lock analysis.
cmake -B build -DBUILD_BENCH=ON
cmake --build build -t bench_bitcoin
After compiling bitcoin-core, the benchmarks can be run with:
build/src/bench/bench_bitcoin
The output will look similar to:
| ns/op | op/s | err% | total | benchmark
|--------------------:|--------------------:|--------:|----------:|:----------
| 57,927,463.00 | 17.26 | 3.6% | 0.66 | `AddrManAdd`
| 677,816.00 | 1,475.33 | 4.9% | 0.01 | `AddrManGetAddr`
...
| ns/byte | byte/s | err% | total | benchmark
|--------------------:|--------------------:|--------:|----------:|:----------
| 127.32 | 7,854,302.69 | 0.3% | 0.00 | `Base58CheckEncode`
| 31.95 | 31,303,226.99 | 0.2% | 0.00 | `Base58Decode`
...
build/src/bench/bench_bitcoin -h
To print the various options, like listing the benchmarks without running them or using a regex filter to only run certain benchmarks.
More benchmarks are needed for, in no particular order:
- Script Validation
- Coins database
- Memory pool
- Cuckoo Cache
- P2P throughput
