Not necessarily - gcc pulls in quite a range of system headers, which
may be cached by the kernel less aggressively than the other stuff
you're keeping in RAM.
I'd recommend running iostat (in the sysstat ebuild) to see at least
what kind of IO is going on here. You may also want to experiment with
remounting e.g., /usr/include on a tmpfs.
