Benchmarking

Bitcoin Cash Node has an internal benchmarking framework, with benchmarks for cryptographic algorithms (e.g. SHA1, SHA256, SHA512, RIPEMD160), as well as the rolling bloom filter, address encoding and decoding, CCoinsCaching, memory pool eviction, and wallet coin selection.

The benchmarks can be run and built using ninja bench-bitcoin. This produces and runs the benchmarking executable src/bench/bench_bitcoin.

The output will look similar to:

More benchmarks are needed for, in no particular order:

  • Script Validation
  • Coins database
  • Memory pool
