Programeri projekta Pyston, koji nudi visoko performantnu implementaciju programskog jezika Python uz kori\u0161tenje suvremenih JIT kompajlerskih tehnologija, predstavili su pro\u0161irenje Pyston-lite s implementacijom JIT kompajlera za CPython. Dok je Pyston odvojen od izvornog koda CPython i razvija se samostalno, Pyston-lite je oblikovan kao univerzalno pro\u0161irenje namijenjeno povezivanju sa standardnim interpreterom Python-a (CPython). <\/p>\n

Pyston-lite omogu\u0107uje kori\u0161tenje osnovnih tehnologija Pyston bez zamjene interpretera, putem instalacije dodatnog pro\u0161irenja uz pomo\u0107 upravitelja paketa PIP ili Conda. Pyston-lite ve\u0107 je dostupan u repozitorijima PyPI i Conda, a za instalaciju dovoljno je izvr\u0161iti naredbu \u201epip install pyston_lite_autoload\u201c ili \u201econda install pyston_lite_autoload -c pyston\u201c. Ponudena su dva paketa: pyston_lite (izravno JIT) i pyston_lite_autoload (izvodi automatsku zamjenu JIT prilikom pokretanja Python procesa). Mogu\u0107e je i programski upravljati uklju\u010divanjem JIT iz aplikacije bez instalacije modula autoload, koriste\u0107i funkciju pyston_lite.enable(). <\/p>\n

Iako Pyston-lite ne pokriva sve dostupne optimizacije u Pystonu, njegova upotreba omogu\u0107ava pove\u0107anje performansi otprilike 10-25% u usporedbi sa standardnim Python 3.8. U budu\u0107nosti se planira prenos ve\u0107ine optimizacija prisutnih u Pystonu u Pyston-lite, kao i pro\u0161irenje podr\u017eanih verzija CPython (prvo izdanje podr\u017eava samo Python 3.8). Od globalnijih planova isti\u010de se suradnja s CPython timom na implementaciji novih API-ja za JIT, \u0161to \u0107e omogu\u0107iti potpuniju kontrolu rada Python-a. Razmatra se uklju\u010divanje predlo\u017eenih promjena u granu Python 3.12. U idealnom scenariju razmatra se mogu\u0107nost prenosa cijele funkcionalnosti iz Pyston-a u pro\u0161irenje, \u0161to bi omogu\u0107ilo napu\u0161tanje odr\u017eavanja vlastitog forka CPython. <\/p>\n

Osim Pyston-lite, projekt je tako\u0111er izdao a\u017euriranje punopravnog paketa Pyston 2.3.4, u kojem su predlo\u017eene nove optimizacije. U testu pyperformance verzija 2.3.4 je br\u017ea od verzije 2.3.3 otprilike 6%. Ukupna dobitak performansi u usporedbi s CPython-om procjenjuje se na 66%. <\/p>\n

Dodatno se mogu spomenuti optimizacije razvijene unutar ciklusa razvoja CPython 3.11 u glavnom projektu, koje su u nekim testovima omogu\u0107ile pove\u0107anje performansi na 25%. Na primjer, u CPython 3.11 pove\u0107ana je efikasnost ke\u0161iranja stanja bajtkoda osnovnih modula, \u0161to \u0107e ubrzati pokretanje skripti za 10-15%. Poziv funkcija je zna\u010dajno ubrzan, a dodani su specijalizirani brzi interpretatori tipi\u010dnih operacija. Tako\u0111er se radi na prijenosu nekih optimizacija pripremljenih projektima Cinder i HotPy. <\/p>\n

Dodatno, u okviru projekta nogil, radi se na eksperimentalnom re\u017eimu izgradnje CPython bez globalne blokade interpretera (GIL, Global Interpreter Lock), koja ne dozvoljava paralelni pristup zajedni\u010dkim objektima iz razli\u010ditih niti, \u0161to ote\u017eava paralelizaciju operacija na vi\u0161ekernelskim sustavima. Kao alternativno rje\u0161enje problema s GIL-om razvija se mogu\u0107nost vezivanja pojedina\u010dnog GIL-a za svaki interpreter koji se izvr\u0161ava unutar procesa (u jednom procesu mo\u017ee raditi vi\u0161e interpretera, ali efikasnost njihovog paralelnog izvo\u0111enja ovisi o GIL-u).
