Is there a way to improve ccache's cache hit?
Here are my current stats:
There's stuff in the man page about adding "fuzziness", something like fuzzy_ctime, etc, that I thought would improve cache hits, but it ended-up lowering it...
Now it's just basically the default config, here's my config file that has the "sloppiness" I meant... and also my headers because i'm awesome.
What do you guys have? Anything I could do better?
Also, for the record, I wanted to make something like that, but it involved changing the way make handles the port tree and the work directory... I essentially wanted to make it so make and/or portsnap would compare the new distfiles's contents to what was already there, and just overwrite what had been changed... I'm not sure if it would've been better than ccache or not...
