--- Comment #1 from Carlos Alberto Lopez Perez <clopez at igalia.com> ---
Some more stats:

* Rebuilding the Debug build from ccache without Debug fission:
  - Time to build = 06m:42s
  - Size of WebKitBuild/Debug = 16GB


* Rebuilding the Debug build from ccache with Debug fission:
  - Time to build = 04m:05s
  - Size of WebKitBuild/Debug = 8.9G


The time to build is mostly linking time, since I'm rebuilding from previously generated ccache DB. And this is on a system with an SSD. On a system with a rotational media it will probably improve build times further.

Its also nice that the size of the build output has been reduced (almost to half). This will help to save disk space also.
