This is a known efficiency bug:

https://krbdev.mit.edu/rt/Ticket/Display.html?id=6782

I will see what I can do about resolving the primary KDC only when 
needed, but can't make any guarantees for the short term.  For the 
moment the only workarounds are the configuration ones you've probably 
already considered (changing krb5.conf or using a local DNS resolver 
with negative caching).
