USENIX SREcon APAC 2022: Computing Performance: What's on the Horizon

Brendan Gregg

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

Running A Page Speed Test: Monitoring vs. Measuring

Smashing Magazine

In contrast, tools like DebugBear and WebPageTest use more realistic throttling that accurately reflects network round trips on a higher-latency connection. This is high-quality data from actual website visitors, for example based on Google’s Chrome User Experience (CrUX) Report. Real usage data would be better, of course.
