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.

Running

After compiling bitcoin-core, the benchmarks can be run with:

src/bench/bench_bitcoin

The output will look similar to:

Notes

More benchmarks are needed for, in no particular order:

• Script Validation
• CCoinDBView caching
• Coins database
• Memory pool
• Wallet coin selection
