+# Pprof
+
+There is a built pprof server to faciliate profiling the program.
+
+Note it does not affect performance unless the server is queried.
+
+We assume Gossamer runs on `localhost` and the Pprof server is listening
+on the default `6060` port.
+
+You need to have [Go](https://golang.org/dl/) installed to profile the program.
+
+The easiest way to visualize profiling data is through your browser.
+
+The following commands are available and will show the result at [http://localhost:8000](http://localhost:8000):
+
+```sh
+# Check the heap
+go tool pprof -http=localhost:8000 http://localhost:6060/debug/pprof/heap
+```
