Why does Figma's prototype preview latency increase when multiple users interact concurrently?

When multiple collaborators edit a Figma file and simultaneously trigger the same Interactive Component, the prototype preview often exhibits noticeable latency that does not appear with single‑user interaction. The goal is to understand whether this delay stems from increased collaboration sync traffic, rendering pipeline contention, or another internal bottleneck. Constraints include the need to reproduce the issue without altering file permissions or using external tools, and the uncertainty around which specific interaction patterns (e.g., rapid taps vs. sustained holds) exacerbate the effect. What factors contribute to the observed latency increase? How can we isolate whether the delay originates from Figma's collaboration sync versus its rendering pipeline? Are there known thresholds for concurrent interactions that trigger this behavior?
