The updater monitors a tasks after they start to make sure they don't fail immediately. The default time interval for this is 30s. However, this is a bit long for synchronous updates to wait. Reduce it to 5s. Users who would like a longer monitoring period should specify their own value, or ideally use a health check in the service definition.

Looks fine to me. |

Should this impact performance at all, actually? |
|
It shouldn't really impact performance. The main user-visible impact is that "update state" will switch to "complete" 5 seconds after updating the last task (if all goes well), instead of 30 seconds after. Right now this is a relatively mundane detail, but the WIP PR I have open in docker that shows progress bars for updates makes it a much bigger deal. |
