Subject RE: Lucene Java Vs .Net
Date Wed, 13 May 2009 20:39:01 GMT
I think, at first,  it is just a simple comparison of results of the same
code with the same index on the same hardware.

After then, some optimizations specific to to .Net or Java (or more complex
test cases) can be thought.

My issue with this type of comparison is the difference in hardware.  Small
differences can make a big impact.

What are you doing to make sure this is apples to apples as far as hardware
goes?

Hi Shashi

general@lucene.apache.org  could  be a good place to discuss your tests and
results.
I eagerly wait your results.

Hi, I am bumping up this thread to see if there are any further inputs
on this. I was planning on running a benchmarking test for .NET vs
Java for both Indexing & Querying (single field, multi field, span
etc.), and would be happy to share my results. I would be using the
PubMed corpus of biomedical literature and running indexing on a few
million articles.

I would be interested to see if others are running on other corpora,
sharing ideas would be very helpful IMHO.

Regards,
Shashi
