Synthetic interaction sub-parts on Wix sites
50.4% of audited sites (1,687) complete synthetic interactions in under 35ms (96% good field INP, 79ms median), while the 6.8% exceeding 110ms reach 91ms median field INP (92% good INP).
15.7% of Wix sites use 65 to 110ms lab interaction duration synthetic interaction sub-parts, and 97% of those sites have a good INP, against 96% of all Wix sites.
INP pass rate
Sites with 65 to 110ms lab interaction duration synthetic interaction sub-parts have a good INP most often: 97%, against 96% of all Wix sites. Sites with 35 to 65ms lab interaction duration lab interaction time have it least often, at 96%.
Synthetic interaction sub-parts usage
Under 35ms lab interaction duration is the most used: 50.4% of Wix sites. 65 to 110ms lab interaction duration is 15.7% of Wix sites.
Synthetic interaction sub-parts per framework
On React, 50% of sites use under 35ms lab interaction duration synthetic interaction sub-parts, and 96% of React sites have a good INP, against 96% of all sites.
Synthetic interaction sub-parts or the framework
Does the framework explain the synthetic interaction sub-parts difference?
On React, 97% of sites with 65 to 110ms lab interaction duration synthetic interaction sub-parts have a good INP, against 96% of React sites with under 35ms lab interaction duration. Within React, sites with 65 to 110ms lab interaction duration and under 35ms lab interaction duration have a good INP about equally often.
How input delay, processing, and presentation add up
Every user tap or click waits for background main-thread tasks to finish (input delay), runs event callbacks (processing), and recalculates styles and paints the next frame (presentation). Across 1,687 sites (50.4%) under 35ms in lab interactions, 96% pass field INP at an 79ms median, versus 92% (91ms median) on the 6.8% (229) exceeding 110ms.
Understanding synthetic interaction sub-parts
Keep event handler processing lean and yield before forcing layout or paint updates so total interaction latency stays well below the 200ms INP threshold. Across all audited sites, 50.4% finish under 35ms (96% good INP, 79ms median) versus 6.8% above 110ms (92% good INP, 91ms median).
