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!

“Khamenei Will Die Soon”
The Khamenei regime will not be able to maintain control over Iranian society after the violent suppression of the latest wave of protests, one of the country’s leading film-makers has predicted.
“It is impossible for this government to sustain itself in this situation (...) Khamenei will die soon”, the director Jafar Panahi said.
“They know it too. They know that it will be impossible to rule over people. Perhaps their only goal right now is to bring the country to the verge of complete collapse and try to destroy it.”
Protests caused by an ailing economy have swept through Iran since late December and were met with deadly crackdowns by the security forces over the weekend, with reports of more than 2,500 people killed.
A internet blackout imposed last Friday, which blocked 95-99% of the country’s communication network, was a “sign that there would be a very big massacre on the way”, Panahi said.
“But we never predicted that the crackdown would have such dimensions and numbers.”
In December the director was handed a one-year prison sentence in absentia on charges of creating propaganda against the political system, but he has stated his intention to return to the country.
He has been jailed twice, for protesting against the detention of two fellow film-makers who had been critical of the authorities in 2022, and for supporting anti-government protests in 2010.
Panahi said while the collapse of the government led by the clerical leader, Ayatollah Ali Khamenei, was inevitable after the latest bloody suppressions, its timing was impossible to predict.
He warned western governments about engaging with the clerical regime as rational actors.
“In other dictatorships around the world, you will see that there will be at least a few people who will act based on rationality and who will not let it get to this point,” he said, speaking via his interpreter Sheida Dayani.
“But unfortunately in this system there is no rationality. All they can think of is crackdown and how they can stay in power even just one more day. The last thing they’re thinking about is the people.”
Asked whether Pahlavi could be trusted to oversee a post-regime transition, he said this would be for the people of Iran to conclude.
“Whether we agree with Pahlavi or not, we know that the overwhelming majority of the population of Iran want the current regime to go.”
