Are you opening your IndexReader with readOnly=true? If not, you're
likely hitting contention on the "isDeleted" method.
When you run with a "normal" directory, either on a traditional hard
drive or SSD device, do you use NIOFSDirectory? That removes
contention, but, it only works on non-Windows platform due to a
long-standing bug in Sun's JRE.
It was a long lunch, actually Im just creating an IndexSearcher directly
on a file
i.e Searcher searcher = new IndexSearcher(indexDir + "/track_index");
I was struggling to see how to create an NIOFSDirectory until I realised
I needed Lucene 2.9, which Ive done as follows
Searcher searcher = new IndexSearcher(IndexReader.open(new
NIOFSDirectory(new File(indexDir + "/track_index"),null),true)));
Anyway the end result is query times have been reduced from 43 seconds
to 23 seconds, so a pretty good result. (although I dont really
understand why the RAMDirectory method didnt perform at least this well
because it would have no file io contention)
thanks alot Paul
