Hi guys,
We've identified a significant querying performance decrease after
switching from Lucene 1.4.3 to 1.9.1.
It is steadily demonstrated no mater if the concurrent querying threads
are 1, 2, 4 or 8 (or even more) -
If N queries are executed against 1.9.1 for a given time, then 1.4.3

Stanislav,
Could you also try a nightly build to test the later performance improvement
on BooleanScorer2? The nightly builds are here:

The jar is called lucene-core-nightly.jar in the .tar.gz build.

Switch to the old scorer (via BooleanQuery.setUseScorer14(true) )
solved the performance issue - now Lucene 1.9.1 & 2.0.0 perform on the
same load test just as 1.4.3 does
Thanks a lot Yonik!
Any chance there exists a non-professional explanation what's the
difference between old and new boole
Paul,
We are working on delivering the next release by the end of the week so
I have to take care of 2 or 3 issues before I try the nightly build.
I promise to try it and report the results here.
Best,

Paul,
we are using a slightly modified version of Lucene,
so in order to run the performance tests on a nightly build, I need
Lucene's sources, not the compiled classes.
Is there a nice and easy way to get them?
