Yes

No. The subscriber table is never cached. Every authentication request
will cause a lookup in the database.

Thus, Kamailio does not care how many subscribers are in the table.
Regarding load, the only thing that matters is the number of
authentication requests per time interval.

You can not avoid the authentication load for INVITEs, but you can
increase the "idle load" caused by REGISTER requests by increasing the
expire value.
