If you set up a disk cache that's large enough, you shouldn't need
this, as GCC will remain in the cache indefinitely (unless replaced by
a later load).

Please tell more about your system, including what CPU and OS do you
use.  Also, compare the compilation times with the table in chapter 7
of the FAQ and tell how does your system measure up.

In general, any reasonable machine with 12MB should be fast enough.  I
would suggest to bump up the cache to 3-4MB.  And make it use delayed
writes (see section 3.9 of the FAQ), it speeds up things quite a bit.
