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

Assuming encode/decode speeds meet your needs. Encode/Decode Speed. Degree of compression, image quality, and decoding speed are key factors to be considered when comparing image performance for the web. However, the AVIF team is working on improving encoding speeds. A tl;dr of recommendations can be found below.

If those specs sound eerily familiar, it's perhaps because they're identical to 2016's $200USD Moto G4 , all the way down to the 2011-vintage 28nm SoC process node used to fab the chip's anemic, 2012-vintage A53 cores. Recall that single-core performance most directly translates into speed on the web. " package. How bad is it?

I can count on one hand the number of teams I’ve worked with who have goals that allow them to block launches for latency regressions, including Google products. The landing pages of popular tools talk about “speed” without context. That unzips to roughly 2MB of script.
