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!

‘Sharing is off the table’ as #drought reshapes the lives of #Ethiopia’s pastoralists
Pastoralists in Ethiopia’s #Somali region say that worsening drought is eroding traditional systems of sharing that once helped communities survive.
Historically, Somali pastoralists survived drought through strong social networks. These Indigenous climate adaptations were built on an intricate system of mutual aid.
One of the most important systems is known as Gergar, a form of social insurance in which families who lose livestock receive animals from relatives and neighbors to help rebuild their herds.
“When people used to lose livestock, others would help them,” says Mohamed Abdi, a lifelong pastoralism advocate and director at Jijiga University’s Institute of Pastoral and Agro-Pastoral Development Studies. “We would move to relatives or sub clan areas, and they shared water and pasture with us.”

'Our children are next' fear #Kenyans as #drought wipes out livestock
In drought-hit northeastern Kenya, villagers have been forced to drag their dead livestock to distant fields for burning to keep the stench of death and scavenging hyenas away from their homes.
Mandera county along Kenya's borders with Ethiopia and Somalia has seen no rain since May and is now on the point of a full-blown water emergency.
"I have lost all my cows and goats, and burned them here," Bishar Maalim Mohammed, 60, a resident of Tawakal village, told AFP.
In his village, where most are pastoralists relying heavily on their animals, the only remaining bull can no longer stand. He has lain in the same spot for nearly a week, severely dehydrated with bones protruding through his skin, as his owner watches helplessly.

🌎 The Madagascan baobab, sometimes called the “upside-down tree,” stores thousands of liters of water in its massive trunk, allowing survival through severe drought. This clever reservoir keeps it lush while nearby plants wilt. ✨

U.N. warns of Madagascar 'climate change famine'
Madagascar produces less than 0.01% of global carbon dioxide emissions, but amid a fourth year of drought in the Grand Sud region, the U.N. is warning of a 'climate change famine'.
