7.09.2025 состоялся релизPithon 3.14!
На фоне хайпа про NoGIL всё позабыли про другие фичи. Особенно про Multiple Interpreters, который обещает изоляцию процессов но с эффективностью потоков! На сколько действительно это будет эффективно мы узнаем позже, потому что сейчас это лишь первый релиз с ограничениями и недоработками.
Но что там про NoGIL? Теперь этот режим не экспериментальный, а официально поддерживаемый, но опциональный.
Чтобы запустить без GIL нужна специальная сборка. И перед стартом нужно объявить переменную PYTHON_GIL=0
Для вас я собрал готовый репозиторий где достаточно запустить скрпит, который всё сделает:
▫️ соберет релизный Python 3.14 в новый Docker-образ
▫️ запустит тесты в контейнере (GIL, NoGIL, MultiInterpreter)
▫️ распечатает результаты
Тест очень простой, усложняйте сами)
Вот какие результаты у меня:
=== Running ThreadPoolExecutor GIL ON
TOTAL TIME: 45.48 seconds
=== Running ThreadPoolExecutor GIL OFF
TOTAL TIME: 6.14 seconds
=== Running basic Thread GIL ON
TOTAL TIME: 45.54 seconds
=== Running basic Thread GIL OFF
TOTAL TIME: 4.74 seconds
=== Running with Multi Interpreter
TOTAL TIME: 18.30 seconds
Если сравнивать GIL и NoGIL, то на мои 32 ядра прирост х7-x10 (почему не х32? 🤷). При этом нам обещают что скорости будут расти с новыми релизами.
Режим без GIL похож (визуально) на async, тоже параллельно, тоже не по порядку. Но это не IO! и от того некоторый диссонанс в голове 😵💫, нас учили не так!
Интересно, что чистый Thread работает быстрей чем ThreadPoolExecutor без GIL.
Ну и где-то плачет один адепт мульти-интерпретаторов😭 Теперь нужно искать где они могут пригодиться с такой-то скоростью. Скорее всего своя область применения найдется.
Отдельно я затестил память и вот что вышло на 32 потока:
ThreadPoolExecutor GIL ON
305.228 MB
ThreadPoolExecutor GIL OFF
500.176 MB
basic Thread GIL ON
90.668 MB
basic Thread GIL OFF
472.444 MB
with Multi Interpreter
1267.788 MB
Пока не знаю как к этому относиться)
В целом - радует направление развития!

Why am i so addled, i seek retort through this creation.
Can't understand a thing, anymore. I just need Salvation
What am i gonna gain, if anything, why do i need revelation.
I do just fine without mass, getting back to isolation?
Why is it so important, why look for identification?
Is it the curiosity or the fear of seperation?
There is inspiration, there is recreation, there is manipulation, sensation, violation & frustration but is there anything that's necessary? Is there any elevation?
I know it bothers none but please, tell me, where am i heading to, what is my destination?

I mutilate myself, no matter what i do.
Acting all spirit, i maim when I'm disregarded, when I'm passed over.
Acting all foul isn't my cup of tea either, i maim again, i incapacitate either way.
Being ignoble and or moral, both roads are noxious to me. What do i fancy then?
You blemish me, your bygones. I can't condone it. I can't strand you either. You, your, it impedes me, candidly but won't gash you by disclaim, renounce.... Won't? Well, can't is more apt, can't bestow to soar your agony.... But about my torment? I have nowhere to go, no door left open, I'm stuck, stuck with you. I'll dwell, I'll persist, that's what I've been doing, that's what i can keep up with. No possibility, either at whim or reluctantly, i have to adhere, no recourse.... I'd be thrusting here, i don't know the stretch, the extent, maybe perpetuity.

You were fire, i wasn't ice
I was supposed to but it wasn't nice
I was magma that was piquant
Why was our bond so highly turbulent?
The violent gesticulation of air around your flames
Wasn't any good for my fever but i got used to the games
We were bonded the way we weren't meant to be
Was it destiny, i wondered or was it our will that was the key
You're no good for me, i know, said she
But it was too late for her to be set in the world again like a bird, free
If we're meant to do it together, yes my love, we suffer like the way we suffered
You'd be the flame of my candle that demolishes my wax, he uttered
Afterall, diamonds dice diamonds, they are suited together
Shouldn't be befuddled with types different but stay where they belong, forever
