 # Benchmarking p5.js
 
-We have a grunt task that runs performance benchmarks in multiple real browsers on the developers local machine. It will automatically detect which browsers are installed from the following list (Chrome, Firefox, Safari, Edge, IE) and run the benchmarks in all installed browsers and report the results.
-
-Our benchmarking system consists of 3 main components:
-
-1. [Benchmark.js](https://benchmarkjs.com/) - The engine that runs the benchmarks and the framework for defining benchmarks.
-2. [karma-benchmark](https://www.npmjs.com/package/karma-benchmark) - The karma plugin for launching and running the benchmarks in multiple real browsers.
-3. [grunt-karma](https://www.npmjs.com/package/grunt-karma) - The grunt plugin that allows us to define different karma configurations per grunt command.  This allows us to run single benchmarks or groups of benchmarks.
- 
-## Basic instructions:
-### Install the new dependancies
-
-    npm ci
-
-### Do a build, the benchmarks expect a local build of p5.js and p5.min.js
-
-    grunt
-
-### Run a specific benchmark
-
-    grunt karma:<target_benchmark>
-    
-### To run all the benchmarks
-
-    grunt karma
-
-### Example
-
-    grunt karma:random-dev
-
-Outputs:
-```
-Chrome 62.0.3202 (Linux 0.0.0)
-  p5 random() vs Math.random(): Math.random() at 95811115 ops/sec (1.26x faster than p5 random())
-Firefox 56.0.0 (Fedora 0.0.0)
-  p5 random() vs Math.random(): Math.random() at 2367566507 ops/sec (1.14x faster than p5 random())
-
-Done, without errors.
-```
-
-## Adding new benchmarks
-1.  Create a new benchmark file at this path and name format:  bench/*.bench.js
-2.  Write the benchmark here is documentation [karma-benchmark](https://github.com/JamieMason/karma-benchmark/blob/master/README.md)
-3.  Add the benchmark target to `grunt-karma.js`
-
-### Example benchmark [random-fe-off.bench.js]
-
-Here is an example benchmark that compares p5 random() to Math.random() with Friendly Error System disabled. It has two suites one for instanced mode and one using the global window random().
-
-```JavaScript
-p5.disableFriendlyErrors = true;
-
-const p5Inst = new p5();
-
-/**
- *  Instance random() vs Math.random()
- */
-suite('Friendly Errors: OFF, Instance random() vs Math.random()', function () {
-  benchmark('Instance random()', () => p5Inst.random());
-
-  benchmark('Math.random()', () => Math.random());
-});
-
-
-/**
- *  Window random() vs Math.random()
- */
-suite('Friendly Errors: OFF, Window random() vs Math.random()', function () {
-  benchmark('window random()', () => random());
-
-  benchmark('Math.random()', () => Math.random());
-});
-```
-Then you would need to add your new benchmark to `grunt-karma.js`
-
-```JavaScript
-...
-'random-fe-off-dev': {
-    options: {
-      files: [
-        'lib/p5.js',
-        'bench/math/random-fe-off.bench.js'
-      ]
-    }
-  }
-...
-```
-Now you can run your new benchmark with:
-
-    grunt karma:random-fe-off-dev
-
-## Comparing Prod to Dev
-karma-benchmark can load remote files.  So it's easy to include the p5.js prod build and compare it to the dev build.  This is important when you're working on improving performance to compare your changes to what is in production.   To do this simply make two targets in `grunt-karma.js` one for prod and one for dev.
-
-```
-  'random-prod': {
-    options: {
-      files: [
-        'https://cdnjs.cloudflare.com/ajax/libs/p5.js/<%= pkg.version %>/p5.js',
-        'bench/random.bench.js',
-      ],
-    },
-  },
-  'random-dev': {
-    options: {
-      files: [
-        'lib/p5.js',
-        'bench/random.bench.js',
-      ],
-    },
-  },
-```
-You can see that `random-prod` actually loads the latest build from CDN.  Then to compare you can run both targets using:
-
-    grunt karma:random-prod karma:random-dev
-
-## Notes
-I chose to put the grunt-karma tasks in it's own file `grunt-karma.js`  instead of the main `Gruntfile.js`, because as we add more benchmarks overtime the file could grow quite long, and I wanted to keep the main Gruntfile clean.
+Benchmarking has been moved to its own repo available at https://github.com/limzykenneth/p5-benchmark. A overall view of the benchmark result of the latest version of p5.js can be seen at https://limzykenneth.github.io/p5-benchmark/. This is still a work in progress.
