+# Benchmarking rm
+
+Run `cargo build --release` before benchmarking after you make a change!
+
+## Simple recursive rm
+
+- Get a large tree, for example linux kernel source tree.
+- We'll need to pass a `--prepare` argument, since `rm` deletes the dir each time.
+- Benchmark simple recursive rm with hyperfine: `hyperfine --prepare "cp -r tree tree-tmp" "target/release/coreutils rm -r tree-tmp"`.
+
+## Comparing with GNU rm
+
+Hyperfine accepts multiple commands to run and will compare them. To compare performance with GNU rm
+duplicate the string you passed to hyperfine but remove the `target/release/coreutils` bit from it.
+
+Example: `hyperfine --prepare "cp -r tree tree-tmp" "target/release/coreutils rm -rf tree-tmp"` becomes
+`hyperfine --prepare "cp -r tree tree-tmp" "target/release/coreutils rm -rf tree-tmp" "rm -rf tree-tmp"`
+(This assumes GNU rm is installed as `rm`)
+
+This can also be used to compare with version of rm built before your changes to ensure your change does not regress this.
+
+Here is a `bash` script for doing this comparison:
+
+```shell
+#!/bin/bash
+cargo build --no-default-features --features rm --release
+test_dir="$1"
+hyperfine --prepare "cp -r $test_dir tmp_d"  "rm -rf tmp_d" "target/release/coreutils rm -rf tmp_d"
+```
+
+## Checking system call count
+
+- Another thing to look at would be system calls count using strace (on linux) or equivalent on other operating systems.
+- Example: `strace -c target/release/coreutils rm -rf tree`
+
+## Flamegraph
+
+### samply
+
+[samply](https://github.com/mstange/samply) is one option for simply creating flamegraphs. It uses the Firefox profiler as a UI.
+
+To install:
+```bash
+cargo install samply
+```
+
+To run:
+
+```bash
+samply record target/release/coreutils rm -rf ../linux
+```
+
+### Cargo Flamegraph
+
+With Cargo Flamegraph you can easily make a flamegraph of `rm`:
+
+```shell
+cargo flamegraph --cmd coreutils -- rm [additional parameters]
+```
