Perform multiple web requests simultaneously.

Key: MNG-3739
URL: http://jira.codehaus.org/browse/MNG-3739
Project: Maven 2
Issue Type: Improvement
Components: Performance
Affects Versions: 2.0.9
Reporter: Maarten Billemont
Maven's dependency downloading is horribly slow.
It appears to only make one request at a time; often to slow mirrors which take
seconds to respond.
This is not so much of an issue when you use a local repository to keep and
manage your dependencies; though it becomes one again once you leave the
network of that repository and try to access it over the internet.
Maven should make multiple (5 or so; configurable perhaps) requests
simultaneously so that while several are establishing connection, others are at
least already using the available bandwidth. And should mirrors be capped;
other artifacts can already be downloaded from other mirrors to make optimal
use of the bandwidth. Currently only a fraction of the bandwidth capacity is
used; causing an initial build of a large project without a local repository
available to take *for* *ever*. The project I'm working on; I need to make
sure to reserve a day at least should I want to build the code with a client.
