Extreme lag when rendering latex with vimtex

When I try to render latex documents in neovim with vimtex, I consistently see long periods of lag (20-60 seconds) whenever I edit my document and vimtex updates the pdf. I tried disabling all of my plugins and using entirely new configs, and yet this problem persists. Changing computers also does not resolve this issue. My operating system is pop os 22.04. Has anyone else encountered this issue? If so, how did you resolve it?

EDIT I discovered the cause of the issue: I was using biber as backend for the authordate package. I found that by switching to bibtex as an alternative backend the render time reduced from an average of 30 seconds to 9 seconds and the input lag that accompanied that lag disappeared entirely!
