The link doesn't seem to work for me. I also couldn't find the map on Steam or Gamebanana.
From what I remember, Delfino was removed a long time ago. It's two to three times the size of Dust Showdown, most of it is deep water and it's incredibly flat with little to no ground cover. It's a Sniper hell that is prone to stalemates.
Bianco Hills briefly replaced it, but it was also prone to stalemates and had spells and jump pads everywhere.
