-------------------------------------------------------------
Running a test that creates 'n' docs each with an id,name, and a few subjects,
the results are:
[100000] SolrInputDocument: 1828
[100000] LuceneInputDocument: 2499
[100000] DocumentBuilder: 1746
[1000000] SolrInputDocument: 14162
[1000000] LuceneInputDocument: 19764
[1000000] DocumentBuilder: 17127

Surprisingly it looks like:
SolrInputDocument -- fastest
LuceneInputDocument - ~2x slower
DocumentBuilder - ~3x slower
I'm sure the documents I'm building aren't a good distribution of what random
documents would look like - BUT, the other style documents (copy fields, things
with default values, etc) are handled more easily in the already winning

> Key: SOLR-272
> URL: https://issues.apache.org/jira/browse/SOLR-272
> Project: Solr
> Issue Type: Test
> Affects Versions: 1.3
> Reporter: Ryan McKinley
> Attachments: SOLR-272-SolrDocumentPerformanceTesting.patch,

> In 1.3, we added SolrInputDocument -- a temporary class to hold document
> information. There is concern that this may be less then ideal
> performance-wise.
> To settle some concerns (mine included) I want to compare a few SolrDocument
> implementations to make sure we are not doing something crazy.
> I implemented a LuceneInputDocument subclass of SolrInputDocument that stores
> its values directly in Lucene Document (rather then a Map<String,Collection>).
> This is a quick test comparing:
> 1. Building documents with SolrInputDocument
> 2. Building documents with LuceneInputDocument (same interface writing
> directly to Document)
> 3. using DocumentBuilder (solr 1.2, solr 1.1)
