I tried the following steps with both the Cocoa/GNUstep port and the
X11 build on the same machine running Mac OS X 10.5.6.  Both are
compiled from the latest CVS trunk.

  1. Start Emacs with the `-Q' option.
  2. C-x C-f /sshx:remotehost: RET  (remotehost is running Solaris)

The Cocoa/GNUstep port was much slower (~20 sec. to list the home
directory) than the X11 build (< 2 sec.).
