Nothing in your report suggests any PostgreSQL bug.  You might find
useful suggestions on pages like this:

On my Ubuntu machine (running on bare hardware rather than in a
vagrant/virtualbox under OS X) that runs in about 5 ms.  You might
want to check that vagrant is honoring the TCP_NODELAY setting
(which disables the Nagle algorithm).
