Sometimes a bundle update or bundle install can take forever. Its a huge time waster. Did you know you can massively speed this up very easily. Just create or update your
~/.bundle/config and add the following line.
The number you should choose here is 1 less than the number of CPU cores you have. In my case I have a quad core so I use 3 here. If you have hyperthreading choose 2 less than total threads.
# ~/.bundle/config --- BUNDLE_JOBS: '3'
or you can run the following command which will do the above for you.
bundle config --global jobs 3
