From my experience: if you are going to optimize your index after
loading (a good idea for making search as fast as possible) than it does
not matter what you set the merge factor to during the load. If you have
a healthy max buffered docs set, the merge factor will not affect the
speed at all - 10, 50, 90, 120, it does not matter. Whether that is
because a high max buffered causes all of the merges to occur in RAM or
the optimize causes you to pay the dues you got from the altered merge
factor, I do not know. I do know that max merged docs is generally the
biggy for batch loading. Watch out though, setting max merged docs too
high will cause you to miss the speed sweetspot.

Hi,
just to give more info, I am using Lucene.Net 1.3 version, and not
1.9version. I think there is no option of setmaxBufferedDocs() in the
old
version. Can you tell me the best way to speed up the performance.
What are
the parameters that I should set. I know that this depends on the system,
but which parameter exactly speeds up the indexing performance.
Thank you
