No namespaces loaded is not a very good benchmark IMO, a real project will have lots of them.

I've worked on a large project with many namespaces and dependencies and it took about 20 seconds.

That seems pretty slow, I've never had it take more than 5 seconds, even on large enterprise backend services.

Maybe your service was also initializing a lot of state/components on startup?
