В Linux стандартными средствами можно использовать часть оперативной памяти как диск. Для этого требуется указать тип монтирования tmpfs в команде mount
mount -t tmpfs -o size=5G tmpfs /mnt/ram
Теперь путь /mnt/ram можно использовать как обычный каталог. Для чего это может быть нужно?
▫️ Скорость работы с таким каталогом выше чем многие SSD и тем более HDD.
▫️ Если у вас очень быстрый SSD на NVMe M.2 то такой способ особо не прибавит вам скорости, но поможет сохранить ресурс SSD когда требуется обрабатывать очень много мелких файлов и оперативка позволяет выделить нужный объем.
▫️ Оперативка это энергозависимая память, поэтому выключении питания все файлы безвозвратно теряются. Такой "non persistent" каталог гарантирует удаление временных файлов.
Я написал небольшой скрипт для условного теста и сравнения скорости копирования файлов между SSD и RAM.
Вот мои результаты:
Single File Size: 30.0Gb
ssd > ssd: 0:00:12.850 / 2.3Gb/s
sdd > ram: 0:00:06.453 / 4.6Gb/s
ram > ram: 0:00:06.995 / 4.3Gb/s
ram > sdd: 0:00:06.217 / 4.8Gb/s
Dir size: 32.7Gb, File count: 11127
ssd > ssd: 0:00:15.063 / 2.2Gb/s
sdd > ram: 0:00:08.486 / 3.9Gb/s
ram > ram: 0:00:08.032 / 4.1Gb/s
ram > sdd: 0:00:07.026 / 4.7Gb/s
Скрипт для теста ↗️
На моём железе прирост скорости ~2x. Плюс экономия ресурса SSD.
В Windows такой фишки по умолчанию нет, но обязательно найдутся аналогичные решения

On June 19, the Office of the Honorary Consul attended Deputy President Paul Mashatile’s lecture at St. Petersburg University(SPbU)
📍Lecture Topic:South Africa’s G20 Presidency in a Rapidly Changing Global Geopolitical Environment
🔹 Deputy President Mashatile announced that isiXhosa, one of South Africa’s official languages, will be studied at SPbU starting this September.
🔹 He emphasized the importance of expanding African studies programs in Russian universities and welcomed stronger academic ties.
📚 Following the event, we presented SPbU leadership with a copy of M. Maqetuka’s Jim Is Tired of Jo'burg, translated into Russian and published in Yekaterinburg last year.
🤝 We also discussed potential collaboration between SPbU’s Africanists and Ural Federal University’s African Club (learn more: t.me/sarconsulurals/2036).
