I'm describing below an other test with the same physical host and virtual guest. I installed the xfce desktop environment (via tasksel) and I uninstalled all lxqt packages. I disabled the snap user service start (from the xfce session configuration panel). Then, the cold start of the deb package application is down in less than 2 seconds (better). Maybe de xfce desktop environment already loaded a few libraries (libgtk-3-0, ...). In addition, I measured the used memory (free -k) by comparing the "used" memory field before launch and a few seconds after the window appeared. With deb package application : 266 MB. With snap package application : 397 MB (+49%). It seems the deb package application saves memory because it is sharing the libraries with the other applications of the desktop. Note that I didn't count the used memory by the snap machinery (in case you wouldn't install snapd with a deb package application).

When I launch firefox, the delay between my click and the apparition of the window is very long compared to the behaviour of the previous versions of Ubuntu. The deb package is just pulling the firefox snap. Why did you decide this performance regression ?! I don't understand.
