[jira] [Commented] (JENA-412) RETE patch for faster forward rule execution

["Dave Reynolds (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JENA-412?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13606312#comment-13606312 ] 

Dave Reynolds commented on JENA-412:
------------------------------------

Patch looks good to me. The optimization makes sense and the space tradeoff is likely to be reasonable. As Tilo says, all tests pass.

Shall I go ahead and apply it to trunk?

> I would like to like to submit a patch which speeds up forward rule

> It uses only slightly more memory, but reduces the time needed for my

> It passes all tests so far. Am I missing something?
