Yes they are, maybe unix sockets too (not tcp) but yes, there’s a point.

Aren't DB queries generally over TCP? Of course one should OPTIMIZE their DB
queries, but in many cases they're necessary in many cases, right?

Well, you can set up a cluster of background workers and use the normal http_client. That
will speed up the process to read from the network as the network client processes are
freed up by you suspending the transaction and continuing in a background process (which
you need many of). This will make life better in some cases, but not all.
But in high volume, I would not _depend_ on any TCP-based external process, regardless if
it’s HTTP or databases.

TL;DR don't do HTTP queries from Kamailio. Just don’t
