is a fast compiler cache. Whenever an application is compiled, it will cache intermediate results so that, whenever the same program and version is recompiled, the compilation time is greatly reduced. The first time ccache is run, it will be much slower than a normal compilation. Subsequent recompiles however should be faster. ccache is only helpful if the same application version will be recompiled many times; thus it is mostly only useful for software developers.
