Neither in the separate, directly available portal application to install. On my portal I have to go first in the Teams application, and then from here get proposed with a pop up to install the full fat client..... I would prefer to get the option to install team fat client straight from the top level of the portal applications install menu.
Performance has been and continues to be a big focus area for Teams. One main area we have made improvements in is responsiveness for the most frequent user actions of switching between Chat, Channel, and Activity. We are also focused on reducing resource consumption and application load time. More improvements are on the way.
