Julia Benchmarks

Use this skill for all Julia benchmarking work. Pick the workflow first, then open only the matching reference file.

Choose a Workflow

• Quick ad-hoc timing during development:

references/quick-patterns.md

• Writing a benchmark suite:

references/suite-patterns.md

• Full suite example:

references/suite-example.md

• Comparing saved benchmark results:

references/comparison.md

• Benchmark CI with AirspeedVelocity.jl:

references/ci.md

Quick Commands

using BenchmarkTools

v = rand(1000)
@btime sum($v)
@btime sort!(x) setup=(x=copy($v))

julia -tauto --project=benchmark -e 'include("benchmark/benchmarks.jl"); run(SUITE)'
julia -tauto --project=benchmark -e 'include("benchmark/benchmarks.jl"); tune!(SUITE); run(SUITE)'

Notes

• Use $ interpolation in BenchmarkTools unless you deliberately want to time

global lookup.

• Use setup= and usually evals=1 for mutating benchmarks.
• Use a benchmark subproject for repeatable suites and CI.
