Benchmarking
============
Bitcoin Core has an internal benchmarking framework, with benchmarks
for cryptographic algorithms such as SHA1, SHA256, SHA512 and RIPEMD160. As well as the rolling bloom filter.
After compiling bitcoin-core, the benchmarks can be run with:
`src/bench/bench_bitcoin`
The output will look similar to:
```
