In the 0.12.0 branch, [httpz](https://github.com/karlseguin/http.zig)
was added to the perf measurements.
Apparently, somehow this got lost, which is a pity. httpz is
super-promising.
Given the perf benchmarks in [this
PR comment](https://github.com/antonputra/tutorials/pull/280#issuecomment-2362637299),
I would have expected httpz to be on par with or better than zap in our
`measure.sh` tests.
However, on my M3 max mac box, I get the following:
**ZAP**:
```

Which looks way off. I must admit, I might have done a bad httpz
implementation.
Seeking help from @karlseguin. My motivation: route people away from zap
to alternatives like httpz or even zzz, as those are pure zig, and seem
to be of really good performance. I want a world in which we don't have
to resort to C frameworks to do good, zig-worthy servers 😄 to come
true.
This means that all downstream users can simply put:
```zig
exe.root_module.addImport("zap", zap.module("zap"))`
```
in their `build.zig` instead of
```zig
exe.root_module.addImport("zap", zap.module("zap"));
exe.linkLibrary(zap.artifact("facil.io"));
```
