Title:
[snap] On Groovy, Chromium snap takes much longer to load the first
time after reboot
Status in chromium-browser package in Ubuntu:
Incomplete
Bug description:
I upgraded from Focal to Groovy, and now the first launch of the
Chromium snap after a reboot is taking much longer than before. On my
main home laptop it takes over 30 seconds, while under Focal I don't
remember it taking more than 10 seconds.
I tried another computer I could erase. On Groovy that computer takes
nearly a minute to launch the Chromium snap after rebooting. Then I
clean installed Focal on the same machine, and the Chromium snap takes
just under 10 seconds to launch after a reboot. For both I installed
all updates, and I let the computer sit idle for a few minutes after
rebooting to try to rule out other activity.
I haven’t noticed the change for any other snap, although I don’t use
any that I ever noticed as much of a launch delay as Chromium. (VS
Code for one doesn’t seem slower — certainly not taking nearly a
minute — but I haven't done a real comparison like for Chromium.)
