No problem here.  I build Emacs CVS almost every day and have never
experienced such a trouble for years.  That cannot be because I live
in Japan. ;-)

Is visiting the HELLO file (i.e. `C-h h') slow, too?  Is it slow even
in Emacs that is launched by `emacs -Q'?  Otherwise, how about trying
`toggle-debug-on-quit' or ELP?  Cf. (info "(gnus)Troubleshooting")
