	## Capturing pprof data with `lnd`
	`lnd` has a built-in feature which allows you to capture profiling data at runtime using [pprof](https://golang.org/pkg/runtime/pprof/), a profiler for Go. The profiler has negligible performance overhead during normal operations (unless you have explicitly enabled CPU profiling).
	To enable this ability, start `lnd` with the `--profile` option using a free port or add `profile=9736` to your `lnd.conf`.
	```
	⛰ lnd --profile=9736
	```

use of the profiler is mentioned, but the information is out of date.
