Yusuke Endoh c55b5f1062 [rubygems/rubygems] Avoid duplicated generation of APISpecification objects ... As far as I could see, `Gem::Resolver::APISpecification` objects are supposed to be immutable. If my guessing is correct, then we can cache and reuse its instances for performance. At least, `rake` passes on my machine. Before this change: ``` $ time ruby -I lib bin/gem install --no-doc aws-sdk Successfully installed aws-sdk-3.0.1 1 gem installed real 0m37.104s user 0m36.952s sys 0m0.333s ``` After this change: ``` $ time ruby -I lib bin/gem install --no-doc aws-sdk Successfully installed aws-sdk-3.0.1 1 gem installed real 0m23.905s user 0m23.740s sys 0m0.365s ``` https://github.com/rubygems/rubygems/commit/7e8fbba85c		2020-09-28 14:54:22 +09:00
