> Outputting every "loaded" entry in the table is excessive, especially for 
> tables with multiple simultaneous bulk imports and multiple references to the 
> same file.  This can cause performance problems.  Even when the log level was 
> reduced, there was blocking within log4j.  By doing that check once outside 
> the loop and only logging at trace level, bulk import performance improves 
> for such usages.
