Emacs manipulate files with long-lines very slowly.

[Hongyi Zhao]

Dear Kenichi,

Now, I've a tex source file which is written on Microsoft Windows.  When I
open it with Emacs on my Ubuntu Linux, because the linefeed is different between
Windows and Linux/Unix, so the file will have very long lines in it.  Even I
use the *M-q* and *truncate long line* command, I find the Emacs is always
manipulate the file too slowly to tolerate.

But I can open it with gedit and edit it very quickly, is there any tricks
to solve the problem or some bugs in Emacs?

Attached is my tex file.

病起多情白日迟，强来庭下探花期。
雪消池馆初春后，人倚栏杆欲暮时。
乱蝶狂蜂俱有意，兔葵燕麦自无知。
池边垂柳腰支活，折尽长条为寄谁？
