mikehearn commented on issue #10: [MRESOLVER-7] Download dependency POMs in 
parallel v2

   It looks like this has bit-rotted again. It'd be really nice to get this in.
   
   Some classes have moved into a sub-package in #12, so now package-private 
visibilities are getting in the way. I wanted to try it out and see how much 
difference to speed it made, so I just quickly undid #12. 
   
   For me it seems to roughly double the speed of artifact fetch. It'll 
probably make a much bigger difference on higher latency links. Nice work!

>             Project: Maven Resolver
>          Issue Type: Improvement
>    Affects Versions: Aether 1.0.2
>            Reporter: Harald Wellmann
>            Priority: Major
>
> h3. Background
> When building a project with dependencies not yet available in the local 
> repository, I noticed that Maven 3.3.9/Aether 1.0.2 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.
