If you have enumeration enabled the purge is not enabled to improve
performance but to make sure objects which are deleted on the LDAP
server are deleted in SSSD's cache as well. So it is part of the
enumeration functionality and cannot be disabled.
In general we do not recommend to enable enumeration only if there are
specific reason, e.g. legacy applications. May I ask if you have
enumeration enable and if yes, why?

You can increase the debug_level and inspect the logs covering the time
of the high CPU load. For this you can add 'debug_level = 9' to the
[domain/...] section, restart SSSD and let it run for a couple of hours.
Then remove the 'debug_level' option and restart SSSD to avoid further
