Hello all:
I asked this question a few months ago, but no one responded. I'm hoping to
have a little better luck this time. :-)

It emacs takes a long time to load/open a c-mode file, especially if there
are already existing c-mode buffers in emacs. The problem/issue is two fold:

1. When I load a c-mode buffer(.c, .h, etc), emacs attempts to fontify the
buffer several seperate times before actually displaying it. I don't think
that is normal behavior but please correct me if I am wrong. Could there be
something in my configuration that is causing this?

2. The bigger issue is that when I load the file, emacs goes through each
c-mode buffer already open and fontifies it. This can take quite a bit of
time if I have many files open, which is most often the case. Some times I
wait as long as 5-7 seconds from the time that I "open" a file to the time
that it actually displays. This is quite annoying.

I can see in the mode-line as emacs goes one by one fontifying my c-mode
buffers before loading the file desired. Below is the output of the
*Message* buffer with my notes interleaved.

Can someone please help me out here?? Thanks in advance!!!

Have you tried it without Semantic?

Actually, I figured out what my problem was.
I had a function that I added to the c-mode-common-hook. This function
contained about 10 different requires and some other stuff. Every time I
opened a c-file this was apparently doing "something" that caused the
fortifying...

Instead of doing through the function and add-hook, I simply run this
function once when emacs starts and now I see no delay whatsoever.

Thanks for the help, anyway. Take care.
