Exactly, the 8MB file was just a simple and easy to reproduce example, that I could use in a small benchmark in order to get some figures. Given that you're using the right font (such as 6x13 ou the bitmap=20 version of courier), even scrolling though a file whose lines are 1000=20 characters long will feel painfully slow with Emacs 23, while it was perfectly smooth=20 with previous versions. But I have sometimes to open log files containing lines that can be=20 tens of thousands characters long. For such files, Emacs is totally unusable,=20 every move in the file resulting in a long hang.
