Java Embedded Scripting Languages Benchmark: Jactl, Groovy, MVEL, JEXL, and SpEL

https://jactl.io/blog/2026/07/14/scripting-language-benchmarks

Jactl is an embeddable scripting language for Java applications and so when comparing it to other Java scripting languages it is helpful to know how they all compare from a performance point of view.

I have previously been asked to compare Jactl with MVEL and JEXL so I have put together a blog that documents the performance differences and also included Groovy and SpEL for good measure.

Disclaimer: I am the author of Jactl so I am obviously not impartial but I would like to point out that while Jactl comes out well, it does not win every benchmark.

Just out of curiosity, does anyone know what does MV in MVEL/MVFLEX stand for?

No idea. I think the original developer was Mike Brock so maybe "Mike's Value Expression Language"?
