In a nutshell:
- composer vendor directory cache
- dist-mode for composer update
- GitHub oauth. You need to set a token on GITHUB_OAUTH_TOKEN variable. Mark it as private to secure it.
- Lowest deps mode to check composer dependencies going right.
- Some Travis optimizations for composer. Some time composer could be long to resolve and consume huge memory
I have some another optimizations idea but I'll talk about it later on another PR. ;-)
