Why We CareThe Ruby Language
The RubyLanguageRubinius is a faithful implementation of
the Ruby Language
Rubinius is a drop-in replacement for MRI 1.8.7
The RubyLanguage
Why We CareDrop-in Replacement
Drop-in ReplacementFull method compatibility
via RubySpec
Drop-in ReplacementMajor C-API compatibility
Drop-in ReplacementMajor C-API compatibility
with some caveats
Why We CareImprove Ruby
Improve Ruby
Ruby should be goodenough to use as its own
underpinnings
Improve Ruby
MRI’s core (Array, Hash, etc) contains no Ruby
Improve Ruby
Strive for scalability and performance for
the Ruby language
Why We CarePerformance
Performance
MRI’s implementation ofRuby is slow
Performance
Prevalence of C extensions demonstrate MRI’s slowness
Performance
Strive to bring Rubyitself up to speed
Why We CareFast Ruby
Fast Ruby
Use established techniques to make Ruby itself fast
Fast Ruby
Compile Rubyto machine code

Why We CareFaster Ruby for All
Faster Ruby for All
Capable of running Ruby code
Faster Ruby for All
Capable of running Ruby codeup to 100x faster than MRI
Faster Ruby for All
Helps change Ruby’s standing in the programming world
Why We CareManage Memory Better
ManageMemory Better
Very fast object allocation
ManageMemory Better
All objects areextremely lightweight
ManageMemory Better
All objects areextremely lightweight56 bytes vs 500 bytes
Manage Memory Better
Compact and releasememory to OS
Why We CareBetter Memory Usage
BetterMemory Usage
MRI’s GC is broken
