A node.js module for microbenchmarking which includes:
This module is primarily intended for my personal consumption and grew out of the need to easily create, execute and archive microbenchmarks which help guide implementation decisions when performance is a priority. It's creation was also a partial learning experience in further understanding the optimizations that V8 makes on your JS code.
That said, the code found here was thrown together very quickly (a few hrs) and is not documented nor the prettiest src in the world.
Finally, we all know microbenchmarks should be taken with a grain of salt and used in accordance with project goals... This is standard stuff, so no further divulgence.
A sample of microbenchmark results can be found under the results directory.
The easiest way to run the microbenchmarks is to just clone the repo:
Then install the dependencies:
And finally run the test suite:
The module is also package via npm and can be installed with:
npm install microbench
To run the benchmarks:
The module contains a simple
microbench binary to run benchmarks
which can be found under the
/bin directory of the module.
It supports the following options:
Usage: microbench [options]Options:-h, --help output usage information-V, --version output the version number-b, --benchmarks <path> directory containing benchmark js files [./benchmarks]-a, --archive [path] archive results in markdown format [./results]-g, --grep <pattern> select benchmarks by name or pattern-u, --ungrep <pattern> unselect benchmarks by name or pattern-o, --only <pattern> only run categories who's name includes the pattern-s, --skip <pattern> skip categories who's name includes the pattern
Run all benchmark js files under
microbench -b /home/boden/projects/js/benchmarks
Run only benchmark js files which contain
simple in the name found
microbench -b /home/boden/projects/js/benchmarks -g simple
Run all benchmark js files which don't contain
long in the name found
microbench -b /home/boden/projects/js/benchmarks -u long
Run all benchmark js file which contain
type in the filename and
who's category contains the string
microbench -g type -o prototype
microbench uses a cli-table
to display output:
You can ask it to archive your bench results in markdown format using the
-a option. For example to run all benchmark js files under
and archive them under
microbench -a /tmp/benchmark/results
