> ----------------------------------------------------------
>
> Key: MNG-7182
> URL: https://issues.apache.org/jira/browse/MNG-7182
> Project: Maven
> Issue Type: Improvement
> Affects Versions: 4.0.0-alpha-1
> Reporter: Guillaume Nodet
> Assignee: Guillaume Nodet
> Priority: Major
> Fix For: 4.0.0-alpha-1, 4.0.0-alpha-2, 4.0.0

>
> The new build/consumer POM introduced in Maven 4 is currently based on SAX
> parsing while the POM and other modello based resources are all parsed using
> the XPP3 StaX parser. This leads to the POM being parsed, transformed and
> serialised to string using SAX, then parsed again StaX. The performance
> penalty is quite big when having lots of projects in the reactor.
> This ticket aims at using a single step based on StaX parsers, allowing
> on-the-fly transformation / parsing in a single step, thus having nearly no
> performance drop compared to the current state.
