[jira] [Commented] (GROOVY-10471) Performance regression for XmlBuilder from groovy3

["Paul King (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-10471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17488082#comment-17488082 ] 

Paul King commented on GROOVY-10471:
------------------------------------

I thought I might be able to observe a difference between 3.0.9 classic and indy and that might explain some of the difference but I noticed a similar trend even though the bytecode produced by 3.0.9 indy and 4.0.0 for the XmlBuilderBench class is essentially the same. We'll need to look deeper.
