I think it took so much time, because it's merged too ofter.
try to increase IndexWriter.mergeFactor (but be aware of 
TooManyOpenFiles Exception when setting too high)  (default 10)
and try to increase IndexWriter.minMergeDocs (consume more ram, but 
works faster). (default 10)

playing a bit with this parameters you can speed up your indexing process.
