While the numbers are likely to change over time, at the time of writing the overhead for `krt` is roughly 10%:

```text

Controllers/krt-8     13.4ms ±23%
Controllers/legacy-8  11.4ms ± 6%

### Future work

#### Object optimizations

	// Only log conversion webhook traces that exceed a 8ms per object limit plus a 50ms request overhead allowance.
	// The per object limit uses the SLO for conversion webhooks (~4ms per object) plus time to serialize/deserialize
	// the conversion request on the apiserver side (~4ms per object).
	defer span.End(time.Duration(50+8*objCount) * time.Millisecond)

	// TODO: Figure out if adding one second timeout make sense here.
