[Freeipa-users] FreeIPA 3.3 performance issues with many hosts

[Dominik Korittki]

Thanks for the info, Tomas.

I will definitely try this one out! Couldn’t wait for it to be released 
for CentOS if it really does what the changes you mentioned describe :-)

We would like to have hostgroup of 10.000 hostmembers or even more in 
one group. We currently split these group into multiple smaller groups 
with max 1000 members, because adding, modifying or removing a members 
of a large group (~7k hostmembers) takes around 7 seconds (removing one 
host from the group alone).

Kind regards,
Dominik Korittki
