### Measure Parsing Performance

Source: https://github.com/jcwasmx86/mesonlsp/blob/main/CHANGELOG.md

This script measures the time it takes to parse a Meson build file 100 times for each version of the language server. It redirects output to /dev/null to focus solely on execution time.

```bash
echo v1.0
time for i in {0..9}; do
	echo $i
	# Will internally parse the tree 100 times
	# Including converting to an AST and doing
	typeanalysis/typechecking
	# => 10 * 100 = 1000 iterations
	../v1.0 --path ./meson.build >/dev/null 2>&1
done
echo v1.1
time for i in {0..9}; do
	echo $i
	../v1.1 --path ./meson.build >/dev/null 2>&1
done
```

### Track Peak Heap Memory Usage

Source: https://github.com/jcwasmx86/mesonlsp/blob/main/CHANGELOG.md

These commands use heaptrack to profile the Meson LSP executable and then extract the peak heap memory usage from the profiling results. This helps in identifying memory consumption patterns.

```bash
heaptrack ../v1.0 --path meson.build
heaptrack_print heaptrack.v1.0.somepid.zst | grep peak.heap
heaptrack ../v1.1 --path meson.build
heaptrack_print heaptrack.v1.1.somepid2.zst | grep peak.heap
```

--------------------------------

### Measure Compile Time

Source: https://github.com/jcwasmx86/mesonlsp/blob/main/CHANGELOG.md

This command measures the clean compile time of a project using Swift. It removes the build directory and then compiles the project in release mode with static Swift standard library.

```bash
swift build -c release --static-swift-stdlib
```
