> Project: Solr
> Issue Type: Task
> Components: Schema and Analysis
> Reporter: Robert Muir
> Assignee: Robert Muir
> Fix For: 3.1

> The example schema should use the lucene core PorterStemmer (coded in Java by
> Martin Porter)
> instead of the Snowball one that is auto-generated code.
> Although we have sped up the Snowball stemmer, its still pretty slow and the
> example should be fast.
> Below is the output of ant test -Dtestcase=TestIndexingPerformance
> -Dargs="-server -Diter=100000"
> These results are consistent with large document indexing times that I have
> seen on large english
> collections with Lucene, we double indexing speed.
