Benchmarking

Litecoin Core has an internal benchmarking framework, with benchmarks for cryptographic algorithms (e.g. SHA1, SHA256, SHA512, RIPEMD160), as well as the rolling bloom filter.

Running

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

src/bench/bench_Litecoin

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
