      It looks as if PRT_COUNT_OCCUPIED is set to 1 by default. This enables accounting code which keeps track of how many entries in an RSet are occupied. Unfortunately, said accounting code is updated using a CAS which can be a performance / scalability bottleneck.

      Thanks to Anders Astrand for pointing this out.
