You probably don't want to touch indexer.termIndexInterval and indexer.maxMergeDocs (determines the max size of an individual segment).
Why is maxMergeDocs 50 by default? Should not this value be much higher?
I found how to calculate the number of opened files But how could I calculate the memory which would be used?And is there any possibility to calculate how much files nutch will create while indexing in the peak?
Many thanks Matthias
