8.4 parsecs away

Travel
| | The 1980s and 1990s saw the genesis of Perl, Ruby, Python, PHP and JavaScript: interpreted, dynamically-typed programming languages which favored ease of use and flexibility over performance. In many ways, these programming languages are a product of the surrounding context. The 90s were the peak of the dot-com hype, and CPU clock speeds were still...

Benchmarking CRuby, MJIT, YJIT, JRuby and TruffleRuby · On the Edge of Ruby
10.3 parsecs away

Travel
| | In this blog post we benchmark many Ruby versions and the latest Ruby Just-in-Time compilers (JITs) on the newest Ruby benchmark suite, yjit-bench. As a teaser, the geometric mean speedups compared to CRuby 3.1 on these 14 benchmarks are: MJIT 1.26x, YJIT 1.39x, JRuby 1.86x and TruffleRuby 6.23x. Read on to find more about the benchmarks and gain insights on these speedups. This blog post is also available on Medium.
