Zhvilluesit e projektit Pyston, q\u00eb ofron nj\u00eb implementim me performanc\u00eb t\u00eb lart\u00eb t\u00eb gjuh\u00ebs Python, duke p\u00ebrdorur teknologji moderne t\u00eb kompilimit JIT, prezantuan shtes\u00ebn Pyston-lite me implementimin e kompiluesit JIT p\u00ebr CPython. Ndryshe nga Pyston, q\u00eb \u00ebsht\u00eb nj\u00eb dege e kodit burimor CPython dhe zhvillohet ndarazi, Pyston-lite \u00ebsht\u00eb krijuar si nj\u00eb shtes\u00eb universale, e destinuar p\u00ebr t'u lidhur me interpretuesin standard Python (CPython). <\/p>\n
Pyston-lite ju ofron mund\u00ebsin\u00eb p\u00ebr t\u00eb p\u00ebrdorur teknologjit\u00eb baz\u00eb t\u00eb Pyston pa e nd\u00ebrruar interpretuesin, p\u00ebrmes instalimit t\u00eb nj\u00eb shtese shtes\u00eb p\u00ebrmes menaxherit t\u00eb paketave PIP ose Conda. Pyston-lite \u00ebsht\u00eb tashm\u00eb i vendosur n\u00eb depozit\u00eb t\u00eb PyPI dhe Conda, dhe p\u00ebr ta instaluar mjafton t\u00eb ekzekutoni komand\u00ebn «pip install pyston_lite_autoload» ose «conda install pyston_lite_autoload -c pyston». Jan\u00eb ofruar dy paketa: pyston_lite (p\u00ebrs\u00ebrit\u00ebs JIT) dhe pyston_lite_autoload (b\u00ebn automatizimin e fiksimit JIT gjat\u00eb fillimit t\u00eb procesit Python). \u00cbsht\u00eb e mundur gjithashtu t\u00eb menaxhohet programatikisht aktivizimi i JIT nga aplikacioni pa instaluar modul\u00ebn autoload, duke p\u00ebrdorur funksionin pyston_lite.enable(). <\/p>\n
Megjith\u00ebse Pyston-lite nuk mbulon t\u00eb gjitha optimizimet e disponueshme n\u00eb Pyston, p\u00ebrdorimi i tij mund\u00ebson rritjen e performanc\u00ebs p\u00ebrreth 10-25% n\u00eb krahasim me Python 3.8. N\u00eb t\u00eb ardhmen, planifikohet transferimi i shumic\u00ebs s\u00eb optimizimeve t\u00eb pranishme n\u00eb Pyston n\u00eb Pyston-lite, si dhe zgjerimi i versioneve t\u00eb mb\u00ebshtetur CPython (l\u00ebshimi i par\u00eb mb\u00ebshtet vet\u00ebm Python 3.8). Nd\u00ebr planet m\u00eb t\u00eb gjera, p\u00ebrmendet bashk\u00ebpunimi me ekipin e CPython p\u00ebr implementimin e API-ve t\u00eb reja p\u00ebr JIT, q\u00eb do t\u00eb lejoj\u00eb nj\u00eb kontroll m\u00eb t\u00eb plot\u00eb mbi funksionimin e Python. Diskutohet p\u00ebrfshirja e ndryshimeve t\u00eb propozuara n\u00eb deg\u00ebn Python 3.12. Idealisht, shqyrtohet mund\u00ebsia e transferimit t\u00eb gjith\u00eb funksionalitetit nga Pyston n\u00eb shtes\u00eb, q\u00eb do t\u00eb lejoj\u00eb largimin nga mb\u00ebshtetje e forks vetjake CPython. <\/p>\n
P\u00ebrve\u00e7 Pyston-lite, projekti gjithashtu ka l\u00ebshuar nj\u00eb p\u00ebrdit\u00ebsim t\u00eb paket\u00ebs s\u00eb plot\u00eb Pyston 2.3.4, n\u00eb t\u00eb cil\u00ebn jan\u00eb ofruar optimizime t\u00eb reja. N\u00eb testin pyperformance, versioni 2.3.4 \u00ebsht\u00eb m\u00eb i shpejt\u00eb se l\u00ebshimi 2.3.3 me rreth 6%. P\u00ebrmir\u00ebsimi i p\u00ebrgjithsh\u00ebm i performanc\u00ebs n\u00eb krahasim me CPython \u00ebsht\u00eb vler\u00ebsuar n\u00eb 66%. <\/p>\n
Shtes\u00eb mund t\u00eb p\u00ebrmendet optimizimet n\u00eb zhvillim brenda ciklit t\u00eb zhvillimit t\u00eb CPython 3.11 n\u00eb projektin kryesor, t\u00eb cilat n\u00eb disa teste arrit\u00ebn t\u00eb rrisin performanc\u00ebn me 25%. P\u00ebr shembull, n\u00eb CPython 3.11 \u00ebsht\u00eb rritur efikasiteti i keqmenaxhimit t\u00eb gjendjes s\u00eb bytecode t\u00eb moduleve t\u00eb baz\u00ebs, q\u00eb do t\u00eb p\u00ebrshpejtoj\u00eb p\u00ebr m\u00eb shum\u00eb 10-15% nisjen e skenar\u00ebve. \u00cbsht\u00eb p\u00ebrshpejtuar ndjesh\u00ebm thirrja e funksioneve dhe jan\u00eb shtuar interpreter\u00eb t\u00eb shpejt\u00eb t\u00eb specializuar p\u00ebr veprat tipike. Po ashtu, po zhvillohet puna p\u00ebr t\u00eb transferuar disa optimizime, t\u00eb p\u00ebrgatitura nga projektet Cinder dhe HotPy. <\/p>\n
Nj\u00ebkoh\u00ebsisht, brenda projektit nogil po zhvillohet nj\u00eb modalitet eksperimental i nd\u00ebrtimit t\u00eb CPython pa bllokimin global t\u00eb interpretuesit (GIL, Global Interpreter Lock), q\u00eb nuk lejon qasje t\u00eb paralele n\u00eb objektet e ndara nga thread t\u00eb ndryshme, \u00e7ka pengon paralelimin e operacioneve n\u00eb sisteme me shum\u00eb b\u00ebrtham\u00eb.
