Gentoo's Portage 3.0 Stabilized With Much Faster Dependency Calculations
Portage 3.0 removes Python 2.7 support as a significant change but more pressing to end-users is faster dependency calculations. Portage 3.0 should be 50~60% faster for dependency calculations.
This big speed-up comes by making use of the lru_cache functionality in Python 3.2 and newer. The developer who worked on the support found that emerge now dropped from about five and a half minutes to just over three minutes on his ThinkPad notebook running Gentoo.
