Not exactly. Only link to the cache root is copied and some cache elements may not be garbage-collected. > Running `memory-report` indicates that each indirect buffer has the same > memory blueprint. > This becomes a massive issue with large org files. > > My in my 160 000 line org file, the org element cache takes 100 mb, and so > each new indirect buffer consumes an additional 100 mbs of memory. This has to be a bug in `memory-report'. Most of the cache elements will be referenced by link and thus there should be double-counting going on somewhere. > I also wonder if this means the caching is performed by each indirect buffer > independently, and doesn't carry over. Caching is using base buffer actually. I guess we can explicitly set reference to the cache root to nil in indirect buffers. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
