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

Army Chief #JosephAoun has officially been elected as #Lebanon’s new president, marking a significant moment in the country’s political landscape. Despite being a political newcomer, Aoun’s position as head of one of Lebanon’s most respected institutions has bolstered his appeal.
Widely regarded as the favored candidate of both the United States, a staunch supporter of the Lebanese army, and regional power Saudi Arabia, Aoun is seen as the best-equipped to navigate Lebanon through its fragile ceasefire and crippling financial collapse.
Turning 61 on Friday, Aoun, known for his "personal integrity," is now tasked with stepping into the void left by Michel Aoun—no relation—whose presidency ended in October 2022
Lebanese daily @alakhbarnews reported that #SaudiArabia remains firm in its stance, maintaining economic pressure on #Lebanon.
According to visitors to #Riyadh, the kingdom has conveyed that it will not contribute "a single penny" to Lebanon’s reconstruction efforts.
Well-informed sources indicate that President #JosephAoun indirectly received this message during his meeting with Saudi Crown Prince #MohammedbinSalman earlier this month.
Additionally, he was reportedly met with a firm Saudi refusal to lift the travel ban on its citizens visiting Beirut.
During their discussions, bin Salman reportedly questioned Aoun on whether he could guarantee the safety of Saudi nationals traveling along Beirut’s airport road, which is lined with images of #Hezbollah and Iranian leaders. He remarked, “At the very least, remove the pictures.”
Upon his return, Aoun relayed this request to Speaker of Parliament #NabihBerri, inquiring about the possibility of reducing the number of such images along the route.
Why do you think Saudi Arabia cares about images displayed in another country? Share your thoughts with Hoopoe.
Following a two-year vacancy, the Lebanese Parliament has elected #JosephAoun as the new President of the Republic. Here's what you need to know about him.
