Subject svn commit: r506093 - in /lucene/java/trunk/contrib/benchmark: ./ src/java/org/apache/lucene/benchmark/byTask/ src/java/org/apache/lucene/benchmark/byTask/feeds/ src/java/org/apache/lucene/benchmark/byTask/programmatic/ src/java/org/apache/lucene/bench...
Date Sun, 11 Feb 2007 18:59:23 GMT
Author: gsingers
Date: Sun Feb 11 10:59:22 2007
New Revision: 506093

URL: http://svn.apache.org/viewvc?view=rev&rev=506093
Log:
Applied 788 and 790 from Doron Cohen.  Ran both the micro-standard and the task runs and results
look reasonable.

Thanks, Doron
