Subject [jira] Commented: (JCR-2625) spi2davex: reduce memory footprint of Node/PropertyInfoImpl
Date Mon, 17 May 2010 13:53:42 GMT

    [ https://issues.apache.org/jira/browse/JCR-2625?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12868224#action_12868224

Stefan Guggisberg commented on JCR-2625:

> Looks good to me. Do the davex integration tests still pass with the patch applied? 


> Furthermore, did you check the impact of the StringCache on memory and performance? There
is a similar mechanism in place already for NameFactoryImpl which works on Name instances
instead of Strings.

the StringCache drastically reduces the number of (redundant) String instances, thereby reducing
memory consumption.  
i didn't notice any negative impact on performance.
