Auto-completion of bibtex entries slowed down

[W-L]

Hi!
I'm using this great plugin in combination with a bibtex file exported from Zotero that is continuously being synchronised. This worked great so far with TeXiFy, i.e. I add or edit entries in Zotero and the bibtex file is automatically updated, which is usually reflected in the TeXiFy auto-completion hints almost immediately.
However, over the last few days I noticed this workflow slowing down considerably. After adding new items in Zotero the changes are synchronised to the bibtex file as expected, but they either do not appear in the auto-completion suggestions of TeXiFy or there are no suggestions at all anymore. Sometimes I also notice that tab-completion of the \parencite command itself takes multiple seconds. I am wondering if this has to do with the size of the bibfile continuously increasing and it having to be re-indexed every time or something along those lines?
Starting a new project with a minimal bibfile restores the original behaviour. Using a smaller bibfile alongside a large one does not seem to speed things up though.
I lack the understanding of what's going on behind the scenes to investigate any further but would be grateful if this can be resolved somehow? Or whether there are some logs I can look at/useful minimal reproducible examples I can put together?
Thanks a lot

It sounds like a plausible problem, but how much bibtex entries are we talking about?

Also, I forgot how Zotero works but can we easily get a library of that size to test with?

I have two files with approximately 250 entries each in the project; does not seem too excessive? Not sure if they are completely re-written on every change, or whether that would make a difference for TeXiFy.

Thanks, that certainly is not very large at all. I'll see if I can reproduce

This might be helpful: a large sample library with ~5k entries: https://gist.github.com/retorquere/d003bcc307befdba1e7661c7a0def5e1
Importing it requires the Better BibTex extension for Zotero though (https://retorque.re/zotero-better-bibtex/), which is also what I use for the synchronised exports.

Thanks very much for your time, let me know if I can help
