Hi@all
 
I am getting strange performance measures on Lucene 4.4.0, maybe someone can 
explain this:
 
The following syntax leads to pretty slow queries on my machine(16ms for every 
execution):
 
theSearcher.search(theQuery, null, theSearcher.getIndexReader().maxDoc());
 
but the following syntax leads to an average execution time of 2ms:
 
theSearcher.search(theQuery, null, theSearcher.getIndexReader().maxDoc(), new 
Sort());
 
Just by providing an empty Sort() instance, which does not sort at all! The 
executed query is a simple TermQuery, the index contains about 2'000'000 
documents. This is quite strange..
 
Thanks in advance
 
Mirko
