Impressive numbers! The new patch improves RAM efficiency quite a bit even with no term vectors nor stored fields, because of the periodic in-RAM merges of posting lists & term infos etc. The frequency of the in-RAM merges is controlled by flushedMergeFactor, which measures in doc count, right? How sensitive is performance to the value of flushedMergeFactor?
