An empirical guide to the behavior and use of scalable persistent memory

The Morning Paper

higher latency and lower bandwidth)… We have found the actual behavior of Optane DIMMs to be more complicated and nuanced than the "slower, persistent DRAM" label would suggest. The physical media is accessed in chunks of 256 bytes (an XPLine). The read latency for Optane is 2x-3x higher than DRAM.

ChatGPT vs. MySQL DBA Challenge

Percona

ChatGPT: The InnoDB buffer pool is used by MySQL to cache frequently accessed data in memory. If we expand the cache concept more, the buffer pool could be even less if the working set (hot data) is smaller. The answer does not consider the queue or latency of the sample, which could indicate a disk with issues.

A persistent problem: managing pointers in NVM

The Morning Paper

(Byte-addressable non-volatile memory,) NVM will fundamentally change the way hardware interacts, the way operating systems are designed, and the way applications operate on data. The starting point is a set of three asumptions for an NVM-based programming model: Compared to traditional persistent media, NVM is fast.

Front-End Performance Checklist 2020 [PDF, Apple Pages, MS Word]

Smashing Magazine

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.
