Profiling chimera-framework
  1. Make sure you have mongodb, gcc, python & nodejs installed
  2. Clone chimera-framework (git clone git@github.com:goFrendiAsgard/chimera-framework.git)
  3. Go to chimera-framework directory (cd chimera-framework)
  4. Perform npm test to make sure everything is working.
  5. Perform node --prof node_modules/mocha/bin/_mocha
  6. A profile log file will be produced. In my case, the name of the file is isolate-0x2652d80-v8.log.
  7. Make a more readable log file by performing node --prof-process isolate-0x2652d80-v8.log > profile.log.
  8. Open up profile.log with your favorite text editor

Text User Interface VS Graphical User Interface

Text User Interface

Consistant

Simple

Allows you to run many commands in one line

Sys-admins and developers love it

Graphical User Interface

Easy

Intuitive (hopefully)

Allows you to click buttons instead of typing any command
