Anne McCarty, a member of the Developer Relations team at Automattic, explains how performance is measured and prioritized in each Gutenberg plugin release:
“With each release… a performance benchmark is run against the last few releases that compares different response times for a large post (~36,000 words, ~1,000 blocks).”
⌨️ Generally speaking, while the loading time of the editor is important, special attention is paid to typing speed:
“This is a far more important measure when it comes to user experience as this is what allows for the smooth experience when working in the editor.”
