On my test computer at least, today's snap revision 1373 seems to have solved it.
Running `snap run --trace-exec chromium` on a cold boot I get Slowest 10 exec calls during snap run: 0.237s snap-update-ns 0.400s /usr/lib/snapd/snap-confine 0.087s /snap/chromium/1373/snap/command-chain/snapcraft-runner 0.590s /snap/chromium/1373/bin/desktop-launch 0.065s /usr/bin/snapctl 0.114s /snap/chromium/1373/bin/chromium.launcher 0.159s /usr/bin/dbus-send 0.286s /usr/bin/xdg-settings 3.609s /proc/self/exe 5.238s /snap/chromium/1373/usr/lib/chromium-browser/chrome Total time: 6.515s -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1900783 Title: [snap] On Groovy, Chromium snap takes much longer to load the first time after reboot Status in chromium-browser package in Ubuntu: Confirmed 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.)
