Emacs is not optimized for ultra-long lines. Do you find it also slow
editing more normal-looking files?

Could you try
emacs -q -xrm Emacs.FontBackend:gdi
and see whether it makes a difference?

For a while, during the development of 23.1, the new font backend was
really slow on Windows, but currently it is not so (or, at least, we
don't receive many complaints about its speed); though it's true that
it is slower than 22.X; it's the price to pay for much better font
support.
If you find it unbearably slow I'd suggest filing a bug in the Emacs
bug tracker, giving as much relevant information as possible (for
example, fonts used, etc.).
