In a fresh installation of Emacs on a new Windows 7 machine, saving files after editing takes a very long time. For example, saving a 300KB Latex source takes about 7 seconds pretty repeatedly. The disk is running, so there is no spinup time. Editing the same file on my old, slower Windows 7 machine (same speed disk, same init files, but probably version 23.1 or 23.2) took less than a second, never long enough to notice. I saw some mentions of version control slowdowns, but I'm not using such to my knowledge, and setting the switches mentioned in those posts made no difference. I did not see anything in the emacs bug list. Thanks for any help you can offer on this.
