deb vs snap launch speed calculator
fresh restart of ubuntu 19.10.
Gnome calculator installed as both deb package and snap package.
Deb package launched first, snap after.
Time profiling is less dramatic, but the difference is still dramatic:
$ time snap run gnome-calculator [snap first run]
^C
real 0m10.627s
user 0m0.391s
sys 0m2.012s
$ time snap run gnome-calculator [snap second run]
^C
real 0m3.061s
user 0m0.278s
sys 0m0.248s
$ time gnome-calculator [deb first run]
^C
real 0m2.834s
user 0m0.241s
sys 0m0.076s
