Ruby vs Python: Performance Comparison Link to heading

Summary Link to heading

Ruby wins across all three benchmarks when using optimized implementations.

Benchmark Python Ruby Winner
JSON Parsing 0.998s 0.709s Ruby
Prime Calculation 2.808s 0.155s Ruby
Async I/O 0.044s 0.022s Ruby

Ruby is faster in all three areas.

1. Data Parsing Link to heading

Ruby wins by –yjit

Python: json module
Ruby: json module with YJIT

  • 500K records serialized, filtered, and summed
  • Ruby ~29% faster

2. Calculation Link to heading

Ruby wins by method

Python: Native prime checking
Ruby: Sieve of Eratosthenes with YJIT

  • Count primes up to 1,000,000
  • Ruby ~18x faster

3. Concurrency Link to heading

Ruby wins by tool

Python: asyncio
Ruby: nio4r (EventMachine)

  • 1,000 concurrent simulated I/O operations
  • Ruby 2x faster

Conclusion Link to heading

Python is losing on:

  1. Data Parsing - JSON processing
  2. Calculation - Algorithm-heavy workloads
  3. Concurrency - Async I/O handling

Ruby with optimized tooling (YJIT, Sieve, nio4r) outperforms Python across the board.
