This is annoying... Would be so nice if there were an actual profiler for consing. I tried - (let* ((attributes (file-attributes truename)) + (let* ((attributes (and nil (file-attributes truename))) which should effectively eliminate the calls to `file-attributes' from `find-file-visiting'. The GC time did not change significantly: 916 38% Automatic GC 213 8% + locate-dominating-file 157 6% + abbreviate-file-name 141 5% + inhibit-local-variables-p 120 5% + file-truename 108 4% + dir-locals--all-files 60 2% + file-name-sans-versions 54 2% + insert-file-contents -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at .
