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 bitcoin_bench
After compiling bitcoin-core, the benchmarks can be run with:
src/bench/bench_bitcoin
The output will look similar to:
```
| ns/byte | byte/s | error % | benchmark
|--------------------:|--------------------:|--------:|:----------------------------------------------
| 64.13 | 15,592,356.01 | 0.1% | `Base58CheckEncode`
| 24.56 | 40,722,672.68 | 0.2% | `Base58Decode`
...
```
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
