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!

🖊OPINION | One Hundred Years of British Interference in Venezuela
Declassified UK documents detail how British governments sought to protect oil investments in Venezuela for over a century, including opposing nationalisation and lobbying during Hugo Chávez’s presidency in 2001.

Bonfire Night (Guy Fawkes Night) is held on 5 November in the UK to remember the failure of the 1605 Gunpowder Plot, when a group including Guy Fawkes planned to blow up the Houses of Parliament and kill King James I.
The plot was discovered and prevented, and people celebrated with bonfires and fireworks. Today the evening is marked by community bonfires, firework displays, and sometimes effigies of “Guy” burned on the fire. Many children learn the traditional rhyme: “Remember, remember the 5th of November / Gunpowder, treason and plot.”

Question: “Have you noticed any demographic changes in the UK?”
A British man: “Not really…”
Passing English women, wrapped from head to toe, seem to agree with him.

Research has shown that European gas contains high levels of carcinogenic benzene: an excess of carcinogenic benzene has been found in European gas. ⚠️
The average index of the benzene content in British gas exceeded the North American level 37 times, in the Netherlands 66.5 times.
At the same time, the maximum values were recorded in London (200 ppmv) and Amsterdam (73 ppmv), although the maximum norm is 1.6 ppmv. 📊
Benzene belongs to the substances of the first danger class, it is carcinogenic and can cause leukemia, bone marrow and DNA damage.
There is no safe level of exposure to benzene. The study also showed that about 40% of the kitchens inspected in the UK, the Netherlands and Italy have constant gas leaks, even when the stoves are turned off.
In 9% of the houses, the level of leakage was so high that it exceeded European standards for benzene content.

October 11, 2021: Alaska quake, U.S. and Taliban, AstraZeneca, Prince Andrew, California oil spill
1. An earthquake of magnitude 6.8 struck the Alaska Peninsula region, the European Mediterranean Seismological Centre said.
2. The United States said on Sunday the first face-to-face meeting between senior U.S. and Taliban officials since the hardline group retook power in Afghanistan was "candid and professional" and that the U.S. side reiterated that the Taliban would be judged on their actions, not just their words.
3. AstraZeneca's experimental COVID-19 drug has helped cut the risk of severe disease or death in a late-stage study, the British drug maker said, a boost to its efforts to develop coronavirus medicines beyond vaccines.
4. British police said they would be taking no further action after conducting a review of evidence relating to sex crime allegations against Queen Elizabeth's son, Prince Andrew, and the late U.S. financier Jeffrey Epstein.
5. Beaches in a southern California city that were shut because of an oil spill last week are set to reopen, authorities said in a statement.
