I've recently seen several reports of fastly growing profiler storages. Let's compress them when possible.

Locally for the skeleton homepage, a single profile goes from 150k to 15k. Level 3 is producing significant compression ratio while being measurably faster than level 6 (the default), that's why I'm using it.
