h3. Test 4 - Combined search and indexing test
In this test, we are both indexing all of Wikipedia while searching.
The search rate is a constant 10 QPS. The queries in this test are identical
to those run above and they are also unique.
Solr is started using
{noformat}
java -verbose:gc -Xmx256m -Dfile.encoding=UTF-8 -jar start.jar
{noformat}
so I've given it a little more heap because of the memory pressure issue seen
in _Test 3_.
The indexing posts the XML described in _Test 1_ - each file contains 1,000
documents and - different from _Test 1_ we now do a commit after each post. No
optimize is being done.
The test has now been running for 15 minutes and I'll let it run for hours.
I'll post details later. :)

> Perform Kuromoji/Japanese stability test before 3.6 freeze

> Key: SOLR-3282
> URL: https://issues.apache.org/jira/browse/SOLR-3282
> Project: Solr
> Issue Type: Task
> Components: Schema and Analysis
> Affects Versions: 3.6, 4.0
> Reporter: Christian Moen
> Assignee: Christian Moen

> 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.
