Web9 mrt. 2024 · This study proposes an I/O stack that has the advantages of both zero-copy and the use of the page cache for modern low-latency SSD. In the proposed I/O stack, the page cache serves the read request by the application first. Upon a miss, the storage device transfers data to a user buffer directly. Web10 apr. 2024 · DRAM density increases by 40-60% per year, latency has reduced by 33% in 10 years (the memory wall!), bandwidth improves twice as fast as latency decreases. Disk density improves by 100% every year, latency improvement similar to DRAM. Networks: primary focus on bandwidth; 10Mb → 100Mb in 10 years; 100Mb → 1Gb in 5 years. …
