How are you authenticating? Are you using password hashes stored in the
database (MD5 or preferrably SCRAM-SHA-256) or are you authenticating
against an external source (e.g. active directory). If the latter, what
and how? Can you measure how long the authentication takes?
I have seen LDAP authentication against a local AD instance take over
hundred milliseconds, so I wouldn't be surprised if that was the
culprit.

PS: a local connection (ident) takes about 3.5 ms on my (not very fast)
laptop.
