Hi Dominik,

performance issues are a known problem, there has been some work to
improve the performance with respect to large groups:

11bd9d96f191066f7ba760549f00179c128a9787
efcd48ad01a39a67f131a2cea9d54771642222fb

These improvements are in FreeIPA 4.2 only, however, which has not been
released for CentOS7 as of now. You may try to play with FreeIPA 4.2 on
Fedora, see https://copr.fedoraproject.org/coprs/mkosek/freeipa-4.2/.

HTH,
Tomas
