Perhaps your XEmacs was built without Mule. In that case, "M-x
find-file-literally" instead of "C-x C-f" should be as fast as XEmacs.
The reason for this performance hit is that "C-x C-f" by default tries
to detect whether the file has encoded non-ASCII characters, and if
so, decodes them into internal representation used for non-ASCII
characters within Emacs buffers. XEmacs compiled without Mule doesn't
do that, so visiting a large file is faster.
