A number without context is not a conclusion.
The site separates measured output from editorial interpretation. It records the host, publishes repeated samples, names semantic differences and states what each result cannot prove.
See the publication workflowSame work
Variants are compared only after their behavior is documented.
Repeated samples
Medians and middle-spread values replace one-shot screenshots.
Local scope
Findings describe this environment, not every server.
Decision context
Operational guidance includes safety and maintainability.
Editorial synthesis

When the fastest PHP option is the wrong choice
Five cases where correctness, interoperability or failure behavior outrank the lowest median.
What seventeen microbenchmarks taught us
A synthesis of what isolated measurements can reveal—and what they cannot prove.
