How many notes do you have?

[joethei]

My personal vault has 265 notes, which is not that much.

For testing one of the plugins I developed I have a vault with ~12.000 notes, graph view gets a bit laggy, but everything else works fine.

The maxiumum number of notes depends on your system and what plugins you use.
Obsidian has been stress-tested by the devs with 20k notes

Maximum Number of Notes in Vault

We stress tested against 20k Markdown files (found here: https://github.com/Zettelkasten-Method/10000-markdown-files), and it works okay on a relatively fast desktop computer. We’ve done extensive optimization on file explorer and search, but the initial loading and processing could take some time for sure. Haven’t seen real-world cases that would require more, unless you want to for example display Wikipedia inside Obsidian.
