Thanks Adam

I've tried the native windows version and it does not have this problem. But I'm an old school Linux user that is forced to use windows at work. I've managed to set up Cygwin and it works quite well, in fact I think Emacs is working very well except for the issue in this post. Not slow. Thanks anyway. / Johan

This isn't much help, but the best suggestion I have is to try the
non-Cygwin, native Windows build.  I use the Cygwin build myself, but it
is inherently slow compared to Linux builds for some reason.  It takes
probably 10-20 times as long to startup, and everything I do it in it is
slow compared to in Linux.  Maybe the native Windows build will perform
better.
