You are using file + elisp-data containers. file container does nothing when the file is already stored in the cache. elisp-data only writes to index file itself and not to cache. So, some other parts of cache are taking time to write. May you try setting `org-persist--report-time' to t and see what comes up? > That said my org-persist-dir is only 44 MB in size, which isn't > particularly large.

If it is 44Mb of Elisp data in a single file, it might take a while to serialize it for Emacs. Especially in older Emacs versions where the serializer is recursive. -- Ihor Radchenko // yantar92, Org mode maintainer, Learn more about Org mode at <https://orgmode.org/>.
