Those are lookups in the local cache and there should be even an index on those attributes. Is there an application on the IPA server doing heavy I/O or is there a chance that the IPA server is short on main memory and has to swap?
If there is a suffiencent amount of RAM you might want ot try to "Mount the cache in tmpfs" as described in the section with the same name in https://jhrozek.wordpress.com/2015/08/19/performance-tuning-sssd-for-larg....

IO looks fine on the server. Plenty of memory available. I mounted the cache on ramdisk but that didn't resolve the issue.
