ccache + the tarball trick nearly halved the amount of time a tinderbox build cycle takes (from around 180-210 minutes to around 115.) Thanks, Jamesh. Now I’m going to have 50% more logs to delete… currently there are 7.5G of build logs in the tinderbox dir. :)
[Later] Hrm, or maybe I failed math. Seems it actually isn’t helping that much; down to something like 170 minutes from 210 or so. Not bad, but given the massive number of hits ccache -s is showing me, not as much as I’d expected.
