Hello,

Would you folks mind giving me a few tips on performance testing Lucene?  I 
want to test the performance impact of a Directory subclass.

What is a good testing tool to use?  I don't see a great way to get SolrMeter 
to run the max # updates/minute and measure throughput that way.  When I set 
the # updates/minute to a large #, SolrMeter logs NullPointerExceptions.  (I 
assume these are within SolrMeter, as I don't see errors in Solr.)  Mike 
McCandless's nightly Lucene performance tests look good, though I've only just 
started looking at it.

Are there any particularly standard or good test sets?  I'd like to test 3 
scenarios:  indexing only, querying only, and indexing plus querying.  
McCandless's indexing test uses wikipedia, which seems great, but he has a slew 
of tests that are each specific to some querying feature.  I'd like a single, 
general query test.  It's not hard to come up with a decent set of queries, but 
I'd really like something representative of real world queries.  If there some 
standard set of commonly used queries, that would be ideal.

Thanks!

Scott
