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!

🌎 The mysterious "terror bird" Titanis walleri once roamed North America about 2 million years ago. Standing nearly 2.5 meters tall, it was a flightless predator with a massive hooked beak. Fossils show it preyed on small mammals, and its closest living relatives are modern seriemas of South America. ✨

🌎 Ice Age cave lions once roamed across Europe and Asia, hunting mammoths and bison in frigid steppe. Larger than today’s lions, these extinct predators are known from beautifully preserved cave paintings and even mummified cubs found in Siberian permafrost. ✨

🌎 The chambered nautilus, often called a “living fossil,” has survived nearly unchanged for over 500 million years. Its spiral shell and tentacled, squid-like body resemble fossils from the early Paleozoic era. Living nautiluses inhabit deep reefs in the Indo-Pacific and can have over 90 tentacles. ✨

🌎 The Gomphothere, an ancient cousin of elephants, once roamed the Americas with shovel-shaped lower jaws. These extinct giants sported four tusks instead of two, thriving for millions of years before vanishing at the end of the last Ice Age. ✨

🌎 Long before trees, Earth was covered in giant mushrooms called Prototaxites, some reaching up to 8 meters tall. These towering fungi dominated ancient landscapes 420 million years ago, before forests appeared. ✨

🌎 The pikaia, a tiny worm-like creature from 500 million years ago, may be one of our earliest known ancestors. Its flexible, cord-like structure helped pave the way for the backbone found in all vertebrates today. ✨

🌎 Australian megafauna like Diprotodon, the largest marsupial ever, disappeared about 46,000 years ago. These giant wombat relatives weighed up to 2,750 kilograms. The cause of their extinction is debated—some studies suggest climate shifts, while others blame human hunting. Diprotodon fossils have been found at over 100 sites across Australia. ✨

🌎 The mysterious extinction of the “Siberian unicorn,” or Elasmotherium sibiricum, puzzles paleontologists. This massive Ice Age mammal, related to modern rhinos, had a large forehead horn and grazed Eurasian steppes. DNA studies show it survived until about 39,000 years ago—much later than once thought. ✨

🌎 The woolly rhinoceros, Coelodonta antiquitatis, roamed Ice Age Eurasia with a thick fur coat and massive horn. Fossils found in Siberian permafrost show it survived extreme cold; its extinction about 14,000 years ago is linked to climate warming and human hunting. ✨

🌎 The giant short-faced bear, Arctodus simus, roamed North America during the last Ice Age. Standing up to 1.5 meters at the shoulder, it was one of the largest terrestrial mammalian carnivores ever, yet paleontologists debate if it was mainly a predator or a scavenger. Fossils suggest it vanished around 11,000 years ago, along with much other megafauna. ✨

🌎 The Siberian unicorn, or Elasmotherium, was a massive prehistoric rhinoceros with a single huge horn on its forehead. Fossils show it roamed Eurasia until about 39,000 years ago, much later than once believed. ✨
