The record

Purpose: The runtime/pprof package writes runtime profiling data in the format expected by the pprof visualization tool.
CPU and memory profiling: Go’s testing package supports profiling benchmarks with go test flags that write CPU and memory profiles.
HTTP profiles: The net/http/pprof package serves live runtime profiles through HTTP handlers under /debug/pprof/.
Profile types: The documented predefined profiles include goroutine, goroutineleak, allocs, heap, threadcreate, block, and mutex.
CPU profile limit: CPU profiling uses StartCPUProfile and StopCPUProfile because CPU profiles stream output to a writer rather than appearing as a Profile.
Analysis tool: The Go command-line tool interprets and displays profiles of Go programs and can be invoked as go tool pprof binary profile.
Visualization: The pprof command includes a top summary of program hot spots and a web command that opens an interactive graph of hot spots and call graphs.
Trace integration: The HTTP profiling package serves execution trace data for use with the go tool trace command.
Labels: Labels can be attached to contexts and goroutines, and the documentation says currently only CPU and goroutine profiles use label information.
Profile format: Profile.WriteTo can emit a gzip-compressed protocol buffer or a legacy text format with function names and line numbers.
Platform caveat: On Unix-like systems, CPU profiling does not work by default for Go code built with -buildmode=c-archive or -buildmode=c-shared.
Kernel caveat: The documentation cautions that profiles are only as good as the kernel support used to generate them.
License: The package documentation lists the license as BSD-3-Clause.
Profiles: Predefined profiles cover goroutines, memory allocations, OS thread creation, blocking, and mutex contention.
