High-performance Ruby
Run your Ruby code faster on GraalVM's Ruby implementation, TruffleRuby
Benefits
Running Ruby code faster
TruffleRuby is the fastest Ruby implementation for many CPU-intensive benchmarks
Executing Ruby code in parallel
TruffleRuby runs Ruby Threads in parallel, it has no global interpreter lock for Ruby code
Supporting C extensions
Many C extensions work out of the box, including database drivers
Low-overhead interoperability with Java, JavaScript, Python and R
Provided by the GraalVM Polyglot API
Maintaining high compatibility with the standard Ruby
TruffleRuby aims to be fully compatible with the standard Ruby runtime (MRI/CRuby) along with extra functionality provided by JRuby
Providing tooling such as debuggers and monitoring
The tooling support includes a profiler, debugger, VisualVM, and more, and works across languages
Faster Ruby with TruffleRuby and GraalVM
Optcarrot Benchmark
TruffleRuby JVM CE is 4.2x faster than CRuby 3.0 and TruffleRuby JVM EE is 8.2x faster than CRuby 3.0
Rubykon Benchmark
TruffleRuby JVM CE is 7.3x faster than CRuby 3.0 and TruffleRuby JVM EE is 10.6x faster than CRuby 3.0
TruffleRuby is able to run a key production Ruby application almost entirely unmodified from the standard Ruby configuration at Shopify, making it the only realistic option for migrating to a Ruby implementation with genuine potential for seriously increasing the performance and tooling of Ruby.

Try Examples
require 'sinatra'
require 'some-c-extension'
get '/' do
CExtensions.work!
endRun your existing code unchanged, including native extensions
TruffleRuby runs Rails and is the only implementation besides CRuby to pass all RubyGems tests.
