Just to give you some more context, I just did a clean build of WPE
after having done one of WebKitGTK+ (which explains the preprocessed
cached of 5%) and the numbers are:
13 direct hits (0%), 264 preprocessed hits (5%),
5047 misses (95%), 5324 total.
This was a clean build without changing anything in the code:
5269 direct hits (99%), 55 preprocessed hits (1%),
0 misses (0%), 5324 total.
I can tell you that more than 50% for those four minutes were devoted
to CMake configuration and IDL generation. CCache + CMake + Ninja =
profit! and if you add IceCC to the equation for non cached builds in
an office environment, even better.
PS: I had even wrote a patch for build-webkit to show CCache stats if
present long time ago but it was rejected so I wrap my builds with a
run.pl script doing that.
