It's not huge. On my machine, "make -j32" takes about 30 seconds wall time.
But it's still a fairly large yak (e.g. the build system is non-trivial, at lest to me - and it is not cmake-based. There's an external project that provides cmake build files, but I don't know how stable that is) . I would strongly prefer not to shave it at the moment.

A synthetic test would be based on something like this: https://gist.github.com/anonymous/652ff876293730601cccd1091f1ed446 modified to do something sane.
