Dear Stefan, I've tried now to follow as strictly as possible the instruction from info node "(emacs) Sending Patches". * Explanation of change: function `recentf-cleanup' can be very slow when the recentf-max-saved-items is significant, e.g. 60 items. This is due to this that duplicate items are removed with a iterative search (which means that cleanup is made in quadratic time). The change consists in using a search based on a hash table, so that the cleanup is in linear time. Function impacted are function `recentf-cleanup' and a new function `recentf-string-key' is created. * patch made with diff -c is attached. file [d:/msys/temp/recentf.el Fri Sep 11 19:41:51 2009] is download from CVS, and file [recentf.el Wed Sep 2 16:34:04 2009] is the modified one.
