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

🌎 Mirror neurons in the human brain activate both when performing an action and when observing someone else perform that action. These specialized brain cells are linked to empathy, learning, and understanding intentions of others. Mirror neurons were first identified in the 1990s in monkeys before similar systems were found in humans. ✨

There’s definitely a lack of empathy going on with someone here…

🤔FOOD FOR THOUGHT💭
📌 I would like to expose a situation. If your children don't learn with children with special needs at school and have never been taught that not everyone is equal, maybe you should spend 10 minutes today to explain it to them,
📌Because although they don't currently live with these children at school, they will find them in their lives for sure.
📌In light of recent events regarding the exclusion of a child with autism from attending a school trip and a child with Down Syndrome being expelled from dance class because she couldn't keep up with it, I feel the need to share this.
📌There are boys and girls that no one invites to birthday parties. There are special children who want to be part of a team but are not selected because it's more important to win than to include these children.
📌 Kids with special needs aren't weird , they just want what everyone wants: to be accepted!
📌Can I ask a question? Is there anyone willing share this article like I did, for all the special children out there?
📌Please teach your children to be kind to these beautiful children!
📌Everyone needs love and kindness
