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

🚀 Commodities to Outshine Stocks Amid Geopolitical and Economic Turmoil, Says Bank of America Strategist
Bank of America strategist Michael Hartnett has indicated that investors should pivot towards the commodities market in the coming years, as this asset class is poised to benefit from global geopolitical and macroeconomic instability. According to Jin10, the ongoing Middle East conflicts and the race in artificial intelligence have heightened concerns over supply chains. Governments worldwide are striving to curb the soaring prices of energy and other natural resources, which impact industries and consumers, while also ensuring the supply of critical minerals like rare earths, essential for manufacturing and technology.
Hartnett suggests that for the remainder of this decade, commodities will replace stocks as the primary choice for investors seeking to hedge against risks, inflation, and a weakening dollar. This shift is expected as investors move away from equities in favor of commodities, which are anticipated to become the biggest winners in the "buy anything but bonds" trade. The strategist also notes that excessive fiscal expansion could lead to more frequent bear market rallies in government bonds rather than sustained bull markets.
