I had a similar experience and first suspected deferred tabs, reduced them but startup times remained the same.
In my experience, some plugins affect sections like “Workspace” anonymously, and this doesn’t count towards the time of the plugin itself. In my case, disabling or lazy loading certain plugins improved “Workspace” times.
First, try restricted mode to see if you get the same results.
In other cases, disabling a plugin can affect “Workspace” or “Vault” times just by having the associated file in the /.obsidian/plugins folder.
If the issue improves in Restricted Mode, then one of your community-plugins is the culprit. You’ll need to enable them one by one to find the culprit.
Beautiful! I didn’t troubleshoot outside “Workspaces”. The Tasks plugin was the problem, but after an update it’s no longer messing up the startup time. Happy.
