In slow-performance-with-large-vaults/16633/9, it’s claimed that search should be fixed in 0.12, but I don’t see any mention of this in the changelog for 0.12 through 0.12.3, and, after updating to 0.12.3, I don’t see an improvement in search speed.
For comparison, if I use GNU find with this little pair of Bash scripts, I can find about 1300 hits on the word “the” in about eight seconds, in a Dropbox with 513446 files total and 2081 .md files. That’s with 38 lines of code on my part. I guess this wouldn’t be portable to Windows (Mac too? I don’t really know what is and isn’t included in posix-y shell), but it shows what should be possible.
Obsidian takes maybe 5 seconds to start returning results, and I don’t really expect it to continue to show 1300 results in the search sidebar. But, for a simple tag search with a couple hits, it might take a minute to return anything, and five to admit that the search is complete.
Wikilink-completion is right out.
