Ccache hit statistics from a buildbot is probably the least realistic example possible. Of course the hit ratio is almost 100% when it repeatedly rebuilds almost the same source. For normal development builds the hit ratio should be much much lower, for many reasons (building noticeably less often and building when something does change being the primary two). I consider even my 40% hit ratio to be unusually high. The only useful numbers I can see is the ~5% ccache overhead, which should mean here the break even ratio is <10%, which I guess should be doable for LO, but without any real numbers this is still just guesswork. > Note: when icecream is enable configure.in does _not_ auto-enable > ccache (iow if you want ccache _with_ icecream you need to actively > say --enable-ccahe or set up up transparently on your environment I have manual setup for either/both icecream and cccache, if this was directed at me. -- Lubos Lunak l.lu...@suse.cz _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
