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: ``` # Benchmark, evals, iterations, total, min, max, median AssembleBlock, 5, 700, 1.79954, 0.000510913, 0.000517018, 0.000514497 ... ``` 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 Going Further -------------------- To monitor Bitcoin Core performance more in depth (like reindex or IBD): https://github.com/chaincodelabs/bitcoinperf To generate Flame Graphs for Bitcoin Core: https://github.com/eklitzke/bitcoin/blob/flamegraphs/doc/flamegraphs.md
