OK, when you only have as many .cc files as you have CPU cores, you should stop making them bigger. This is not an issue for big projects.
The caching of compilation fails if you touch a central .h file. When you work on projects like that you start dreading a change to the .h files because development slows to a crawl as the compile times explode.
I worked on V8 and over time the .cc files got smaller and the build times got much worse. Some people felt this was neater, but if you are not in an office with 20 beefy workstations using distcc the effect is brutal.
