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 #linux#triks

I rushed down stairs. The wild energy around her was affecting me. Not only affecting me but turning me into the perfect dumbass. So I thought its good idea if I catch up with my buddy before a vapourising. Reaching on the last step, I looked up at the direction of my room. One second... What she is doing in my room? Rubbing the temple of my head, I dismiss all the cascading thoughts and marched towards the kitchen. "Oww, Holy hell" One second I was marching with my head held high and now I was embracing the pavement. Wow just great. I haven't been this lucky in my whole life. And suddenly I was showered with the God's grace. And I don't think I like it. "Sir...what are you doing on the floor" A very confused Lola, inquired with the bucket that she just emptied on me "I'm kissing the floor, Lola" I replied politely, well my system is shaken now, especially the one which is responsible for my emotions and feelings. "How did you fell ?" Vivek asked in very concerned voice, rushing to me. "No Vivek sir he is not fallen, he is just kissing the floor" Lola beamed from somewhere and I didn't even had energy to facepalm. " And why you are wet?" He inquired " Ohh wow he talks " My lips formed in knowing smile, well it's more like a grin. Actually I was just taunting him. for turning my life upside down. A if it wasn't already. "Yeah sir he talks very much and politely" She beamed again from somewhere and I couldn't do anything more than sighing "Why you are wet? " Vivek asked again ignoring Lola. He is really good in ignoring people. "It's God's grace in liquid form" I murmured, sinking my body in floor. "No sir I just dropped water on him that I was using for cleaning" Stupid woman chirped again, it's better if she murders herself because I will do it brutally and she won't like it, I don't even need to say how ruthless I'm, That idiot doesn't know when to use her mouth and mind, but I'm not even sure if she has mind. #Vivektavinita#Review#paragraph#novel
