Testo Nakada commented on MNG-5896:

This issue should be a low hanging fruit to help improve the build time.

> Download dependency POMs in parallel
> ------------------------------------
>                 Key: MNG-5896
>                 URL:
>             Project: Maven
>          Issue Type: Improvement
>          Components: Dependencies
>    Affects Versions: 3.3.3
>            Reporter: Harald Wellmann
> h3. Background
> When building a project with dependencies not yet available in the local repository,
I noticed that Maven 3.3.3 first downloads the dependency POMs _sequentially_ and then proceeds
downloading the dependency JARs with up to 5 threads _in parallel_.
> Due to this, when first building a project with a large number of dependencies, downloading
a large number of small POMs may take a lot longer than downloading the much larger JARs,
or even longer than building the project itself, especially when a repository manager is used
which increases the download latency.
> h3. Enhancement
> Download POMs of (transitive) dependencies in parallel to significantly speed up initial
builds of large projects.
