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

We are grateful to the participants for their strong commitment to enhancing tax transparency and combating cross-border tax evasion. IRAS remains dedicated to collaborating closely with industry partners to facilitate a smooth implementation process.

Ever wondered how Singapore stays at the forefront of global tax cooperation? Our active participation in international discussions is one way we do so 💪 Just a few weeks ago, Deputy Director Pang Cheng Jong and Senior Manager Kenneth Lim from the International Tax and Relations Division represented the #IRASFam at the 48th OECD Working Party 10 meeting, contributing to crucial discussions that shape the future of international tax transparency and compliance.
Our team engaged with the OECD Business Advisory Group on the Amended Common Reporting Standard (CRS) and Crypto-Asset Reporting Framework (CARF), and worked with government delegates to develop interpretative guidance for both standards – work that will directly impact how these frameworks are implemented globally 🌍
Our active participation reflects Singapore’s longstanding commitment to international tax cooperation and reinforces our role as a trusted partner on the global stage 🤝

💫 Proud to share that our #IRASFam represented Singapore at the 18th Automatic Exchange of Information (AEOI) Peer Review Group meeting, where Senior Assistant Director Ang Ming Kwan (International Tax and Relations Division – Exchange of Information Branch) participated as an International Peer Review Assessor alongside colleagues from the Global Forum Secretariat. Our team also engaged in productive discussions on maintaining consistency in peer review standards and made interventions to champion a level playing field for all jurisdictions.
🤝 Building meaningful connections with the Global Forum Secretariat members and fellow tax administrators has been invaluable. These partnerships drive our shared mission of advancing international tax transparency and compliance.

Earlier this month, together with MOF, our colleagues from the International Tax and Relations Division represented #IRASFam at the 20th Working Group on ASEAN Forum on Taxation. This meeting provided a platform for ASEAN Member States to learn about key international tax issues, including tax transparency, Base Erosion and Profit Shifting (BEPS) and UN developments.
During the forum, our team shared Singapore’s approach and progress in implementing the Crypto Asset Reporting Framework (CARF). Tax Director Gordon Cheong highlighted Singapore's enduring commitment to international tax transparency standards on Exchange of Information on Request, Common Reporting Standard and CARF.
We are grateful for this valuable opportunity to strengthen relationships and foster knowledge sharing with our ASEAN counterparts, reinforcing our commitment to regional collaboration in tax administration.
#LifeatIRAS#taxtransparency#ASEANcollaboration
Our team shared Singapore's journey in implementing the Amended Common Reporting Standard (CRS). Manager Nicole Kan highlighted both Singapore’s implementation progress in accordance with internationally agreed tax transparency standards and our philosophy that robust tax transparency standards are best achieved through genuine partnership with industry stakeholders. This collaborative approach has been instrumental in Singapore's successful CRS implementation.
The ASEAN forum reinforced that regional cooperation is essential - through shared experiences in digitalisation, transparency, and tax certainty, ASEAN administrations can build stronger, more efficient systems that benefit businesses and citizens alike 💪

🎤 Assistant Commissioner Angela Ang contributed as a panellist, sharing our insights on the Common Reporting Standard. She wore two hats – one as an AEOI Peer Review Group member and another as an Assessed Jurisdiction.
🤝 Tax Director Gordon Cheong chimed in too, emphasising how we had teamed up with industry partners to implement CRS. He highlighted that we will continue to closely engage and partner with the industry as we implement the amended CRS and CARF in the coming years.
