+## Memory Profiling
+
+Use [Scalene](https://github.com/plasma-umass/scalene) for memory profiling by running the client
+with the `--memprofile` flag. After a few seconds, a browser-based GUI will appear and allow you to
+inspect the CPU usage and memory usage of various calls over time, as well as point to code that may
+create memory leaks. It's also possible to profile specific components, or tune the parameters to profile only specific components, only certain thresholds, and so on.
