Re: open large file with C code: is it realy should be so slow?

[Richard M Stallman <rms@gnu.org>]

    Apparently, the netbook you are using (Lemote Yeeloong) has a 600-800
    MHz processor.  That shouldn't be so slow as to yield 20 second loading
    times.  There's likely something strange going on.  Could you try with
    Emacs 22 and see if the problem recurs there?

Visiting the small .c file below takes around 2 seconds in Emacs 22.
It takes 15 or 20 seconds in Emacs 23.  In both cases I used -Q
and visited the file first thing after Emacs started.

char *p = 0;

main ()
{
  *p = 1;
}
