You should not. But, when it is nil (not default), things will be slow in your scenario. Another thing you can try is setting org-element--cache-self-verify to nil. If it does not help either, please do M-x profiler-start <RET> cpu <RET> [clock in] M-x profiler-report <RET> M-x profiler-report-write-profile <RET> cpu-profile.el <RET> and then share the resulting profile data. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
