> 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.
