Per https://github.com/snapcore/snapd/pull/1984, can you try this with SNAPD_DEBUG_HTTP=3 set in snapd's environment and then journalctl -u snapd? I tried but I'm not seeing any slowness in create-user any more so it's not showing anything very interesting.

> well, the -T makes it pretyt easy to grep for the bigger time hogs Except the time at the front is the relative time since the start of the previous syscall. To find syscalls that take a long time, you need to grep on the time shown at the /end/ of the line. Both are useful, but time /between/ syscalls points to times where the process is doing a lot in userspace. ** Changed in: snappy Assignee: (unassigned) => Oliver Grawert (ogra) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1625698 Title: console-conf on beaglebone takes unbearable long To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1625698/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

running it manually on a completely idling bbb it takes about 30 seconds until i see the UI, watching top at that time the CPU is constantly saturated... note that there is still a lot processes running in the background during boot up though, where the saturated CPU will be acting a lot slower... note also that we usually boot with the performance governor and supposedly only switch to ondemand at the end of the boot ... perhaps this step should be blocked by subiquity somehow, so we keep performance up until we are done with thd configuration to make the CPU react a bit snappier. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1625698 Title: console-conf on beaglebone takes unbearable long To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1625698/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

5-10 *minutes*? I timed it on my dragonboard and it was about 5 seconds. I know the beaglebone is slow but it shouldn't be 60x slower than a dragonboard. I'd love to know where the time is going, maybe probing is really slow or something? Is it similarly slow if you run sudo /usr/share/subiquity/console-conf-tui after the board is set up? I did notice that the create user step was very slow on the dragonboard (about 2 minutes). That's strange because all that console-conf does is run snap create-user, and running that post setup is quite fast (a few seconds). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1625698 Title: console-conf on beaglebone takes unbearable long To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1625698/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
