I stress-tested on a computer with a mechanical hard drive and a computer with a solid-state drive.
Test file：IMF v3 - Advanced Starter Kit
I duplicated the notes file in this vault to test obsidian’s ability to manage a large number of files. In the vault the largest file is 9.16KB and the smallest file is 309 bytes.
On the computer using a mechanical hard drive, when the number of notes reaches 7000 the delay in operation can be felt. It works properly but the experience is not good.
On the computer using a solid-state drive, there is a noticeable freeze when the number of notes reaches about 12,000.
12,000 is a big number, but not enough to use as a second brain.
If I store all my notes in a vault, maybe 12,000 notes will not be reached in two or three years. But if I plan to use obsidian for a lifetime, I have to consider its capacity now. I don’t want to edit and manage my notes in perceptible delay forever when the number of notes exceeds 12,000 in five or ten years.
I would like to know if obsidian performance is still possible to improve.
