If C compilation were I/O bound then ccache would not speed things up. It does. I've used it on my NFS mounted filesystems and it speeds things up there too. T

There is clearly a point where if your filesystem is slow enough that the process does become I/O bound. I have no experience with ClearCase but from what I've heard it's molasses slow and might be to that point.

At that point it became an order of magnitude faster to build over the network than local, because the local file system had no such cache. Anyway this race between speed, space and network performance has been around a while.
