The loading benchmark provides a more balanced picture. While the pure service is still slightly ahead (about 7% faster), it uses about 6% more memory than the impure one.

Memory Usage - Load

Overall, both implementations deliver nearly the same results. But again, the pure one causes a significantly lower system load like in the first benchmark.

We’ll continue benchmarking the remaining endpoints in the next lesson.
