Help me benchmarking Gulp VS Grunt! A summary of the results will be published on my blog (http://www.insertafter.com/blog.html).

bench.sh

#!/bin/bash
# Install the project
git clone git@github.com:ChtiJS/chtijs.francejs.org chtijs
 
cd chtijs
 
# Testing the Grunt build
git checkout master
npm install --quiet
time for a in {1..10}; do grunt dist; done
 
# Copy paste the result as in a comment to this gist formatted as in the first comment
 
# Testing the Gulp build
git checkout gulp
npm install --quiet
 
# in the buffer mode
time for a in {1..10}; do gulp build --prod; done
 
# in the stream mode
time for a in {1..10}; do gulp build --prod --stream; done

### Note ###
# The full potential of stream mode isn't revealed by those tests since there
# is several plugins that do not support streaming yet

PS : For the record, I got some errors while running the benchmark

• gulp.env has been deprecated for gulp in general (I'm using 3.5.2, you actually just need to replace gulp.env with gulp-util.env)
• streams not supported for Browserify for gulp in stream mode

Ok, new benchmarks are irrelevant since the 2 branches diverged now. Thanks for the intent :).

Oops, sorry it took me that long...
