How we measure

For each page, endpoint and backend, the harness attempts 15 recorded renders after 2 warm-up renders. The default is the median, the middle sample after sorting. Choose p95 or p99 in Options to inspect the upper tail. With a small sample, both percentiles can select the same slowest render. This page shows the latest run because its corpus can change.

Wall time

Elapsed time for the render action as reported by the backend, not round-trip time from the benchmark client. Kitesurf's timer covers the request and reading the full screenshot or HTML response. Browser Run reports server-side time around the browser action. Neither includes network time between the client and Cloudflare. The Chrome (cold start) timer begins when Chrome is ready for CDP, so launch time is excluded.

CPU time

Processor time, not elapsed time; time spent waiting does not count. Kitesurf sums CPU across the main Worker, page JavaScript isolates and renderer. Browser Run and Container use their container-level CPU measurements. Chrome (cold start) adds the Node driver CPU to Chrome's CPU.

Memory

Absolute memory at capture, not the increase caused by one page. Kitesurf sums the main Worker, page JavaScript isolates and renderer. Chrome-backed measurements use proportional set size (PSS) across Chrome's process tree.

  • Kitesurf: the total can include memory retained until the page closes.
  • Browser Run: Chrome is reused, so its PSS can include memory retained from earlier pages.
  • Chrome (cold start): each render gets a fresh Chrome process tree.
