Should I use nscd?
As in the linked article explained, sssd and nscd should not be used at the same time as it can result in unexpected lookups. If you need nscd e.g. for caching hosts entry, which sssd does not cache, it is recommended to configure nscd only for hosts and rely on user, group, etc.

Why is Systemd-resolved?
systemd-resolved caches DNS query responses by default. This means that it can quickly respond to repeated queries for the same domains even when they come from different programs on your system. A quick calculation shows that the DNS cache can’t grow to more than 420 kB when used to its fullest.
How does the DNS cache work?
A DNS Cache works by temporarily storing the results of recently browsed websites’ DNS queries, or other FQDNs, on a local file for faster retrieval. Upon generating this historical report, I found that a baseline for DNS lookup is around 50 milliseconds, with peaks between 150 and 200 milliseconds.
What’s the difference between NSCD and SSSD daemons?
The nscd is a daemon that provides a cache for the most common name service requests like passwd, group, hosts, service and netgroup. sssd primarily provides daemons to manage access to remote directories and authentication mechanisms like LDAP, Kerberos, NIS, etc…so it is more about authentication and authorization.
