vips-benchmarks

The goal of this repo is to demonstrate the performance of the libvips library in comparison to other image processing systems. Currently an accent on ruby-vips: Ruby bindings for libvips library, is made.

Be sure to check out the official benchmarks page: VIPS - Speed and Memory Use for complete demonstration of performance and memory usage characteristics of VIPS library.

Performance test design

The repo has folders ruby/, cpp/ and others, each having platform specific scripts using various libraries available for this platform.

Each script is coded to execute the same scenario (see Scenario section).

Root folder contains runner script, running scripts available in all folders.

See "Do it yourself" section for how to run benchmark scenario.

Scenario

Test scenario was taken from Speed and Memory use page from libvips Home page. The test is repeated 10 times.

Do it yourself

git clone https://github.com/jcupitt/vips-benchmarks

cd vips-benchmarks

bundle update

bundle exec ./runner
