SSSD appears to be taking more than 2+ seconds to start and be able to properly respond to queries in an IPA setup.
I saw this in RHEL but, it was suggested that I open an RFE upstream. The version I was using was 1.8.0-17. This was seen on an IPA Master server.
Is it possible to speed this up without sacrificing something?

all the debugging on (which admittedly slows things down quite a bit),
one pass of the principal selection function takes more than a second.
For some reason, we are calling the principal selection twice - I assume
that's for identity and authentication parts of the back end but I could
