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

Five Data-Loading Patterns To Improve Frontend Performance

Smashing Magazine

Caching partially stores your data and is not used as permanent storage. Using the cache as permanent storage is an anti-pattern. Server caches help lower the latency between a Frontend and Backend; since key-value databases are faster than traditional relational SQL databases, it will significantly increase an API’s response time.

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.

Front-End Performance Checklist 2019 [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. On Smashing Magazine, we use the postfix -opt for image names — for example, brotli-compression-opt.png ; whenever an image contains that postfix, everybody on the team knows that the image has already been optimized.
