Subject: render of big header is too slow

Hi,
at now I often edit big enough header files with C code.
font-lock-mode is on.
And when I start scrolling, emacs eats 100% of cpu,
and do something, I suppose syntax highlight (may be there is internal
emacs `top'
to find out what it do?).
Sometimes even single "page up" or "page down" command,
cause 1 minute of 100% CPU eating.
For example, currently openned file is about 368K, 4988 lines.
I play with jit-lock-mode, in most cases for such kind of files it
helps,
but it looks like hack, I need to find suitable timeouts, and they
different depend on machine load.
And I wonder may be I do something wrong,
because of it is strange that on 1913.173 Mhz machine with
1Gb of memory rendering of 4988 lines of code cause such
problems.
PS
I tried GNU Emacs 22.3.1
and GNU Emacs 23.0.60.1 (from cvs)
PS PS
I tried another editors like kate and gvim,
they work as expected take not more then 1-2 seconds to render such
kind of file, and then scrolling works very fast.
