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 usuallyevals=1for mutating benchmarks. - Use a benchmark subproject for repeatable suites and CI.
