   Considering that your request concerns a "Difference" between the two, posting both is
still relevant if anyone is to help you with spotting any notable difference in the two implementations...
   
   Other things that might prove interesting is:
    - Storage information (Storage can in many cases be a bottleneck, this can especially
be the case if you store and retrieve the documents in the index...)
    - Index size (Both for Java and .NET) - That is the files in the index.
    - Memory Capacity and Footprint (Both for Java and .NET)
   
   That being said... Currently 4.8 have full focus, so you may ultimately be better of asking
this on forums such as StackOverflow etc.
   If there is a severe bottleneck in Lucene.NET 3.0.3 I very much doubt that the team will
be addressing that problem at this point though, instead full focus is given to get the 4.8
version out and then likely point to that as a solution instead - Obviously if the problem
can be replicated on Lucene.NET 4.8.0 then it will be addressed.
   
   But posting your code and any other information you could think of that was relevant here
and/or in a StackOverflow question could mean someone could point to something that is not
done in a optimal way. As i said above, we have over 4 times the documents and a huge amount
of fields, and I can't even get near what you describe even with the most evil queries I can
imagine.
