They whole bootup time is much longr than displayed in the analysis. Like many others posted already, loading the cache is taking really long. Its about 95% of the whole startup time.
I also see a reaindexing task ever time I open obsidian again.
This behaviour is quite new and it wasn´t that way 1 day ago. I gues it´s connected to an update or so. I´m also on the latest release 1.0.3 and Obsidian is running on an up-to-date windows 11 64bit (not arm64).
