I don't know anything specific about zapcc but based on the numbers here: http://www.zapcc.com/case-studies/compiling-boost/ http://www.zapcc.com/case-studies/compiling-boost/ even their first compilation (the one you still need to perform when using ccache) is twice as fast as GCC. In any case, I think the primary audience for this is people using clang, not GCC.

You are correct, zapcc should be compared only to clang from the same svn. clang to gcc is another matter altogether. Even in first compilation, zapcc will cache between the first and second files compiled. The only case where there is no caching is when zapccs starts or re-startes, for example when compilation flags are changed.
