Faster RubyMine

Rationale

We want RubyMine to be as fast as possible. There are a number of improvements that can make a big difference to the out of the box experience.

Mechanism

1. Increase Memory
2. Don't index all project directories
3. Disable plugins that you aren't going to use

Increase Memory

Navigate to: Help > Edit Custom VM Options... and enter:

-Xms2g
-Xmx2g

Alternatively, create a rubymine.vmoptions file located in ~/Library/Preferences/RubyMine80

Essentially you want to give RubyMine a JVM with 2g of memory. If you have an especially large project and you want to run code inspections for the whole project, you may have to increase the maximum memory allocation by using -Xmx4g.

Don't Index All Project Directories

See Exclude Directories. Do not skip this step.
