Con un precedente test, avevo riscontrato che JRuby era la massima espressione per quanto riguardava la velocità nell’eseguire codice ruby, surclassando non solo gli altri interpreti C++ e .Net ma azzardando prepotenti confronti con le ultime due incarnazioni di python. Gli script erano questi e li ho rispolverati anche per questo nuovo confronto.
Ora che Rails 3 è stato rilasciato ed uno degli interpreti consigliati è il nuovo 1.9.2, ero curioso di osservare come si comporta la release ufficiale: direi davvero niente male!
Questa volta ho ristretto il numero dei partecipanti alle sole versioni installate con RVM più un paio di versioni windows: JRuby 1.4.0 ed il più usato 1.8.7 mingw32, giusto per avere un metro di paragone.
Distribuzione Linux: Ubuntu 10.4 64bit
Windows XP 32Bit SP3
