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

According to the 2023 Dynatrace CIO Report , 78% of respondents deploy software updates every 12 hours or less. Note : you might hear the term latency used instead of response time. Both latency and response time are critical to ensure reliability. Latency primarily focuses on the time spent in transit.
