You can run bundle install in parallel. This might be helpful for development, where you often install many new gems when switching between projects.

1. Find out the number of processors you have:

lscpu

2. Set the config in your ~/.bundle/config globally (replace 8 with your number of proccessors):

bundle config jobs 8

Note

If you suspect parallel execution for bundling issues, you can try serially with bundle install --jobs 1.
