Can you describe a bit more in detail your IdP configuration? You write
that you have an external LDAP server, is it used for both
authentication and attributes?</pre>

    Yes, for both. It contains users described by five attributes (text
    only: email, name, etc.). and the password, too.<br>

What does the response times distribution look like?</pre>

    According to which parameter? Relatively to the users count, it is
    on the graphs.<br>

In my own load tests, I couldn't get more than 25 logins/second without
response times exceeding the 5s threshold (unsolicited SSO, 1 CPU,
PostgreSQL, external LDAP for authn & attributes)</pre>
