So you know I need Emacs on every PC I use.
On windows7 I stick with a linuxVM when possibile, but sometime you need maximum speed, and EmacsWin32 is a good guy. Then I read the exact description of my problem…
Emacs on my Windows 7 work laptop was annoying slow when starting (around 10s). If closed and restarted, startup was immediate until, after about 30 seconds, it was slow again. According to Google, slowness might be due to failing DNS lookups of the laptop’s hostname.
and I find out this solution: stop netlogon service via a command like
net stop netlogon
The add also this line to your .emacs…
(setq w32-get-true-file-attributes nil)
