}

Field	Meaning
Key	Benchmark name, or "*" for all benchmarks (prof auto). For prof manual, use the file stem (e.g. BenchmarkGenPool_cpu for BenchmarkGenPool_cpu.out).
include_prefixes	If set, only functions whose full name starts with one of these.
ignore_functions	Short names excluded even when prefixes match.

For prof manual, keys are profile file base names, not the Go benchmark name.
