Dear Emacs expert,
I realized that recentf cleanup is very slow when you have a long list
of saved items (e.g. as few as 60). This is because there is a duplicate
suppression based on linear search (quadratic time).
Starting from latest code on CVS I made an optimization using a hash
table, and this solves the issue.
Please find it herein attached.
Best regards,
Vincent.

Could you send it as a patch instead? Otherwise, it's difficult to see
what changes you've made.
