I suspect it is using fontconfig.  I am using a Retina display, but the text in the tabs seems like it’s normal size.  There is a lot of blank space around the text that makes the tab bigger.  In fact the text itself is smaller in the Gtk3 version.  Here are a couple of screenshots.

Hmm, looks like both whitespace and font are larger. What version of Gtk+-3?

You can try fiddling with the tab-label styling in ~/.config/gtk-3.0/gtk.css. There's some guidance in https://developer.gnome.org/gtk3/unstable/theming.html <https://developer.gnome.org/gtk3/unstable/theming.html>.
