Sanne Grinovero resolved ISPN-507.
----------------------------------

    Resolution: Done


Included test code reveals a performance improvement of ~35% on random searches; the test is very simplistic but stresses the methods relevant to this issue. Performance is now very close to the RAMDirectory; looking forward for more extensive benchmarks.
