Improve JaxrsClientReactiveProcessor.setupClientProxies performance

[Postremus]

Description

In my real world application, I noticed that io.quarkus.jaxrs.client.reactive.deployment.JaxrsClientReactiveProcessor.setupClientProxies takes about 10% of my hot reload time. (about 500ms).

However, in that project I do not have any subresources, which seem to take most of the time.. or so I thought.

After a bit of debugging, I figured out that the keycloak-admin-rest-client uses sub resources.

I created a small reproducer project:

kc-sub-slow.zip

With the quarkus-keycloak-admin-rest-client dependency, hot reload takes about 850ms.
Without only about 450ms.

Anything that can be done here to improve this?

JFR recording of the reproducer (first startup + one hot reload). rename .zip to .jfr: repro-startup-and-hotreload.zip

Thanks for the thorough report!

Definitely something to look into!
