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

The whale "0xfb7" closed a $BTC long position with a loss of $3.7M, withdrew all the funds, and deposited $31.7M $USDC into #Wintermute and bought 10,000 $ETH Later converted it into $stETH, and sent it to another wallet where the whale holds 40,060 $stETH…
$NEIRO (Neiro Ethereum) seems to be in an accumulation phase according to our latest on-chain data:
1/ Whale 0x6ab accumulated 17.7M $NEIRO in the last 7 days at an average price of $0.086.
2/ Whale 0x9Ba bought 17.5M $NEIRO on Sept 6 at $0.154. While profitable with $FET, this whale hasn’t fared as well with meme coins.
3/ Whale 0xAB5 accumulated 6M $NEIRO, DCAing over the past month at $0.128, having made good profits with $PEPE in the past.
4/ Whale 0x1ED accumulated 8.6M $NEIRO at $0.116, has sold some without profit, and now holds 5.6M. It has previously profited from $ETHFI, $SYN, and $PENDLE.
5/ Lastly, #Wintermute, a market maker, continues to hold a large amount of 52.97M $NEIRO ($4.97M), ~5.3% of the total supply.
With a market cap still under $100M and recent signs of increased decentralization in the past weeks, will Binance consider listing it on spot after all 🧐?

Multisign 0xbba (likely @MakerDAO) deposited the last 628 $MKR ($1.76M) to #Binance via wallet 0x1cc 8hrs ago!
Over the past 4 months, this multisign deposited all 30,971 $MKR to Binance and #Wintermute at ~$2,972 ($92M), causing price dips each time.
While multisign 0xbba is now out of $MKR, another likely multisign 0x7fd of MakerDAO, which once used wallet 0x1cc, may soon unload its current 5,177 $MKR ($15.1M).
