My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

Our customers who deployed Availability Groups were now using servers for primary and secondary replicas with 12+ core sockets and flash storage SSD arrays providing microsecond to low millisecond latencies. Our design needed to scale and be adaptable to the modern hardware on the market. one without a replica).

From Edge's telemetry, we see that nearly half of devices fall into our "low-end" designation, which means that they have: HDD s (not SSD s). Add to this the fact that desktop devices have a lifespan between five and eight years, on average, and that the P75 device was sold in 2016. That is, what was the average device in 2016?

Back in 2016, I gave a talk outlining the causes and effects of the terrible performance of web apps built using popular tools on the fastest-growing device segment: low-end to mid-range Android phones. In 2016, Jio swept over the subcontinent like a monsoon dropping a torrent of 4G infrastructure and free data rather than rain.

Some of the built-in features ( wal_compression ) have been there since 2016, and almost all backup tools do the WAL compression before taking it to the backup repository. Individual processes generate WAL records, and latency is very crucial for transactions. The actual benefit of compression depends on many factors.
