If you want to measure potential bottlenecks within the software Zettelstore,
there are two [command line](00001004050000) flags for enabling the measurement (also called *profiling*):



Normally, profiling will stop when you stop the software Zettelstore.
The given `FILE` can be used to analyze the data via the tool `go tool pprof FILE`.

Please notice that `-cpuprofile` takes precedence over `-memprofile`.
You cannot measure both.

You also can use the [administrator console](00001004100000) to start and stop profiling manually for an already running Zettelstore.
