Neko Benchmarks
posted on 2005-05-21I just did some benchmarks for a fibonnacci(32) for some languages and different Neko runtimes, and here’s some comparisons (time in seconds) :
- ocaml bytecode : 0.42
- ocaml opt : 0.06
- java -Xint : 0.73
- java JIT : 0.11
- MTSVM : 2.03
- Python 2.4 : 5.83
- PHP 4.3.10 : 16.40
- neko interp : 16.08
- neko ocamlgen bytecode : 9.90
- neko ocamlgen opt : 0.65
- neko VM : 1.91
Theses times only mesure computation time and does not take into account VM startup or bytecode loading. I hope to get around a 10 factor improvment when adding JIT to Neko. That would bring us ahead of the Ocaml bytecode speed which is quite good for a dynamicly typed language with untrusted bytecode. Adding some primitives such as $iadd or $icompare for optimized integer operations might improve a lot also, but will only be available for high level staticly typed programming languages that generate to Neko.
