I'm seeing a high reduction count on the init process ({<0.0.0>), the top 5 ranking for reduction count is below, init's reductions are a bit higher than the other 4 which are poolboy managers.

The init process evaluates the boot script. In a fairly large system, it can be expected to rack up a lot of reductions during system startup. After that, it should stay pretty quiet.

Example, starting a riak node:
(dev1@REDACTED)2> process_info(whereis(init),reductions).

A few minutes later:
(dev1@REDACTED)3> process_info(whereis(init),reductions).
