Anyone have any further details on this?
The first author of the paper is also the founder of the company which
sells the software described, so these benchmarks should not be
considered entirely objective.
That's not to say that IXE is not faster than Lucene, it might well be.
But they do not list any JVM details, the Lucene version or any Lucene
options. Chances are, with a few informed tweaks, one could improve
Lucene's performance on this benchmark. Chances are also that IXE was
configured for optimal performance on this benchmark, since it was
performed by the authors of IXE.
Also note that this is a micro-benchmark, designed to highlight their
skip implementation. A better comparison would average times from a log
of real user queries.
Please feel free to try to obtain the IXE software and perform
benchmarks of your own.
