You can recompile a lot of things, i reccomend Perl, Python, bash, etc.
You will definitely notice a performance increase, you might want to
take some benchmarks before recompiling just to compare gcc vs. ccc :)

hints:

# you can use this simple script to test python, 1000 is the default
# number of iterations, which isnt very much, i changed it to 100000 for
# mine. i think i was pulling approx. 1000 extra pystones a second with
# ccc (faster portage :-))
$ python /usr/lib/python2.2/test/pystone.py

# there are some simple benchmarks for perl in this perldoc page, in the
# EXAMPLES section. also check here http://www.metacard.com/perlbench.html
$ perldoc Benchmark

# you can time some loop or something to test bash, maybe like this...
$ time for ((i=1;i<10000;i++)); do let ++i**i--; done

If you get some interesting results you should post them to the list  :)

You wont be able to recompile any libraries with ccc (openssl,zlib,etc.), 
unless your prepared to recompile everything that links with it (they're
not compatible). 

Good luck :)
