Which profile for production usage?

1

Which configuration profile do you guys use/recommend for production workloads? The default is a recommended one but I really like the addons (grafana, istio-tracing and kiali), does enabling these have a significant impact on performance?

I am just concerned about this line on the page.

This profile enables high levels of tracing and access logging so it is not suitable for performance tests.

You should still use the default profile since it will size the resources correctly for Istio components, but you can add the other components by passing your own overlay file with the bits you want enabled (use https://github.com/istio/operator/blob/33474ff85fd50fc74e75abd26499e3bddba0436d/data/profiles/demo.yaml as a guide).
