I was able to speed up indexing on 64-bit platform by taking advantage of the larger address space to parallelize the indexing process. One thread creates index segments with a set of RAMDirectories and another thread merges the segments to disk with 'addIndexes'. This resulted in a speed improvement of 27%.
