Simon Willnauer commented on LUCENE-2571:
-----------------------------------------
I run batch indexing benchmarks trunk vs. realtime branch with addDocument and
with updateDocument.
For add document I indexed 10M wikipedia docs into a spinning disk reading from
a separate SSD
Here is the realtime graph:
!wikimedium.realtime.Standard.nd10M_dps_addDocuments.png!
vs. trunk:
!wikimedium.trunk.Standard.nd10M_dps_addDocuments.png!
This graph shows how DWPT is flushing to disk over time:
!wikimedium.realtime.Standard.nd10M_dps_addDocuments_flush.png!
for updateDocument I build a 10M docs wiki index and indexed the exact same
documents with updateDocument here are the results:
Realtime Branch:
!wikimedium.realtime.Standard.nd10M_dps.png!
trunk:
!wikimedium.trunk.Standard.nd10M_dps.png!

> We should run indexing performance tests with the DWPT changes and compare to
> trunk.
> We need to test both single-threaded and multi-threaded performance.
> NOTE: flush by RAM isn't implemented just yet, so either we wait with the
> tests or flush by doc count.
