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

While Zionist warplanes rained terror over #Baalbek Lebanon, our children stood tall, not crying, not running, rather shouting from their classrooms: "We shall never be humiliated."
This is the spirit they cannot bomb.
This is the generation they cannot break.
From the heart of Baalbek, under the sound of explosions, rise voices louder than fear, echoing the promise that we will not kneel.
To every child who stood firm today: you are the heartbeat of Lebanon, the voice of dignity, the living proof that resistance is not taught in books; it’s born in the blood of the free.
هيهات منّا الذّلة✊🏻
Lebanon's suffering Roman ruins
Lebanon’s breath-taking Baalbek ruins – once a must-see attraction for thousands of visitors from around the world – lies almost entirely empty as the combined impact of the global health crisis and the country’s deep economic crisis hit the tourism sector.

The Israeli warplanes launched more than 70 airstrikes against Lebanon’s densely-populated Beqaa, Baalbek and Hermel, massacring at least 63 people only on Monday. The Israeli strikes left many more injured and massive destruction across the area.

Watch this to learn how #Zionazi-#propagandists at #Wikipedia are trying to manufacture consent for #Israeli destruction of the ancient city of #Baalbek in #Lebanon
To the #ZioNazi#genocidiares in #Israel, nothing is sacred.
#Baalbek is an ancient #Phoenician city and is home to some of the world’s best-preserved #Roman ruins, such as the Temple of Bacchus.
Baalbek was designated a #UNESCO World Heritage Site in 1984 for its ancient Roman temple complex.
UNESCO describes these temples as “one of the finest examples of Imperial Roman architecture at its apogee” and they draw tourists from around the world.
Tourism supports much of the local population, so naturally the ZioNazis have targetted some of its ancient buildings
The older and more entrenched a building, a street, a monument, the more it is a target.
Erasure and eradication. Displace and replace is the goal.
The world went crazy for the Buddha statues in Bamiyan but remain mute for Baalbek.
