When I open big text file (46M in this case) emacs take long time for

Is this only my case or is emacs in general sluggish with big files?

Have you looked at the output from top? You may be swapping.

I wasn't comparing anything to anything. I don't understand

If he's filled up memory, and the system has swapped the code
EMACS uses to move the cursor to disc, then he may be seeing
lag due to swap time to move the code in and execute it.

That might or might not slow down other applications, depending
on what cache algorithms are in effect. Keypresses don't come
very often.

I second this... look for swapping.
