A website built to be measured.

A controlled workload

The page uses only local, versioned assets. Fixed-size objects test transfer behavior; a no-store response tests an unavoidable origin trip; unique cold paths create repeatable cache misses.

Browser-session probe

Load a realistic 64 KiB JSON resource from this origin and report what the browser observed.

Measurement objects

• 1 KiB immutable object
• 128 KiB immutable object
• 1 MiB immutable object
• Non-cacheable origin response
• 64 KiB cold-path object
