I only have easy access to one machine running Java: my G4 1.67 MHz  
laptop, running Mac OS X 10.4.5.  I agree that it would be very  
interesting to see results from other systems.  If anyone else wants  
to run these, you can grab the source from my subversion repository:

     svn co 
benchmarks benchmarks

You'll need the Reuters corpus (location specified in benchmarks/ 
README.txt).  You'll also need Perl to run the script which  
preprocesses the Reuters corpus.

If you're interested in running the benchmarks for KinoSearch, I  
recommend using the CPAN shell to install it, as it has a few  
dependencies and it's easier to let CPAN handle them.  You'll need a  
C compiler, as KinoSearch is not pure Perl.  The latest official  
release, 0.08, is available with the usual...

     cpan> install KinoSearch

... which will find the tarball <CREAMYG/KinoSearch-0.08.tar.gz>.   
However, for my tests, I'm using a developer's release, 0.09_03,  
which is at least twice as fast as 0.08.  0.9 is also the first  
version of KinoSearch with incremental indexing enabled.  To get  
0.09_03 from CPAN, type...

     cpan> install CREAMYG/KinoSearch-0.09_03.tar.gz

... at the CPAN shell prompt.

If 0.09_03 hasn't made it your CPAN mirror yet, you can also get it  
from <>.
