Performance is design, and every millisecond counts.
Every update in 2025 trimmed Obsidian's load speed. This is quite complex given the number of different configurations and operating systems Obsidian supports.
We employed many different solutions to speed up Obsidian across various syncing methods, operating systems, plugins, vault sizes, etc.
Getting into Obsidian should be instantaneous regardless of vault size. It's absolutely necessary so that ideas can flow without friction.
Obsidian has always been performance-focused, but one problem area was startup time on mobile. That has radically improved over the last few updates, and it's now down under 500ms for almost all vaults, even my large personal vault with over 17,000 notes.
As of Obsidian 1.10 the app becomes usable after initialization and core plugins, the rest loads in the background.
In 1.11 we're shaving off a few seconds with widgets so you can open/create directly from the lock screen. You also have the ability to choose how the app opens by default (e.g. new note, existing note). You can even bind Obsidian to your action button.
There's still more time we can shave off. Believe me, as someone with a large personal vault, I notice every bit of slowness everywhere it happens, and I won't rest until we shaved it all away.
