# ruby/benchmark
|
|
|
|
This directory has benchmark definitions to be run with
|
|
[benchmark\_driver.gem](https://github.com/benchmark-driver/benchmark-driver).
|
|
|
|
## Normal usage
|
|
|
|
Execute `gem install benchmark_driver` and run a command like:
|
|
|
|
```bash
|
|
# Run a benchmark script with the ruby in the $PATH
|
|
benchmark-driver benchmark/app_fib.rb
|
|
|
|
# Run benchmark scripts with multiple Ruby executables or options
|
|
benchmark-driver benchmark/*.rb -e /path/to/ruby -e '/path/to/ruby --jit'
|
|
|
|
# Or compare Ruby versions managed by rbenv
|
|
benchmark-driver benchmark/*.rb --rbenv '2.5.1;2.6.0-preview2 --jit'
|
|
|
|
# You can collect many metrics in many ways
|
|
benchmark-driver benchmark/*.rb --runner memory --output markdown
|
|
|
|
# Some are defined with YAML for complex setup or accurate measurement
|
|
benchmark-driver benchmark/*.yml
|
|
```
|

Usage: benchmark-driver [options] RUBY|YAML...
|
|
-r, --runner TYPE Specify runner type: ips, time, memory, once, block (default: ips)
|
|
-o, --output TYPE Specify output type: compare, simple, markdown, record, all (default: compare)
|
|
-e, --executables EXECS Ruby executables (e1::path1 arg1; e2::path2 arg2;...)
|
|
--rbenv VERSIONS Ruby executables in rbenv (x.x.x arg1;y.y.y arg2;...)
|
|
--repeat-count NUM Try benchmark NUM times and use the fastest result or the worst memory usage
|
|
--repeat-result TYPE Yield "best", "average" or "worst" result with --repeat-count (default: best)
|
|
--alternate Alternate executables instead of running the same executable in a row with --repeat-count
|
|
--bundler Install and use gems specified in Gemfile
|
|
--filter REGEXP Filter out benchmarks with given regexp
|
|
--run-duration SECONDS Warmup estimates loop_count to run for this duration (default: 3)
|
|
--timeout SECONDS Timeout ruby command execution with timeout(1)
|
|
-v, --verbose Verbose mode. Multiple -v options increase visilibity (max: 2)

## make benchmark
|
|
|
|
Using `make benchmark`, `make update-benchmark-driver` automatically downloads
|
|
the supported version of benchmark\_driver, and it runs benchmarks with the downloaded
|
|
benchmark\_driver.
|
|
|
|
```bash
|
|
# Run all benchmarks with the ruby in the $PATH and the built ruby
|
|
make benchmark
|
|
|
|
# Or compare with specific ruby binary
|
|
make benchmark COMPARE_RUBY="/path/to/ruby --jit"
|
|
|
|
# Run vm benchmarks
|
|
make benchmark ITEM=vm
|
|
|
|
# Run some limited benchmarks in ITEM-matched files
|
|
make benchmark ITEM=vm OPTS=--filter=block
|
|
|
|
# You can specify the benchmark by an exact filename instead of using the default argument:
|
|
# ARGS = $$(find $(srcdir)/benchmark -maxdepth 1 -name '*$(ITEM)*.yml' -o -name '*$(ITEM)*.rb')
|
|
make benchmark ARGS=benchmark/erb_render.yml
|
|
|
|
# You can specify any option via $OPTS
|
|
make benchmark OPTS="--help"
|
|
|
|
# With `make benchmark`, some special runner plugins are available:
|
|
# -r peak, -r size, -r total, -r utime, -r stime, -r cutime, -r cstime
|
|
make benchmark ITEM=vm_bigarray OPTS="-r peak"
|
|
```
