.h5 Test setup

My set up is a MacBook Pro running Mac OS X Lion (10.7) with 8GB memory, a Core i7 CPU (4
cores), a 500GB SSD and too many things running.  (The purpose of the test is to test stability
and not to provide accurate performance numbers, although I also hope to do that.)

My java is as follows:

{noformat}
[cm@ayu:~] java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-383-11M3527)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-383, mixed mode)
{noformat}

I've added fields body and title to {{schema.xml}} and they're using the default Japanese
configuration in {{text_ja}}.  The default search field is body.

> Kuromoji might be used by many and also in mission critical systems.  I'd like to run
a stability test before we freeze 3.6.
> My thinking is to test the out-of-the-box configuration using fieldtype {{text_ja}} as
follows:
> # Index all of Japanese Wikipedia documents (approx. 1.4M documents) in a never ending
loop
> # Simultaneously run many tens of thousands typical Japanese queries against the index
at 3-5 queries per second with highlighting turned on
> While Solr is indexing and searching, I'd like to verify that:
> * Indexing and queries are working as expected
> * Memory and heap usage looks stable over time
> * Garbage collection is overall low over time -- no Full-GC issues
> I'll post findings and results to this JIRA.
