I am sorry that I have to revive this thread.
I have a new MacBook Pro 2023 now, with 12 CPU cores. Obsidian still consumes 100% CPU and when I am on battery, the time until empty reduces from 7-8 hours on normal load to 3 hours when Obsidian runs.
It’s the same when I disable community plugins. So it is definitely a bug in core Obsidian.
Is there any way I can debug this and drill down to the part of Obsidian that sucks so much CPU time while apparently doing nothing?
