Filip Pitak commented on MNG-7845:
----------------------------------
[~cstamas] this was the first thing I tried locally (upgrading to latest
versions of maven and add newest version of maven deploy plugin - not
originally used in our projects), however there was no change in speed. When it
comes to Nexus, there was no change on the machine nor nexus itself, which is
why Im assuming theres no issue here ( + the fact that using older version of
wagon helped our situation). By any chance is there a change of upload strategy
security wise? Maybe just bypassing some validification of https or similar
could be the sollution.
> Slow upload of artifacts to remote repository
> ---------------------------------------------

> Key: MNG-7845
> URL: https://issues.apache.org/jira/browse/MNG-7845
> Project: Maven
> Issue Type: Bug
> Components: Deployment
> Affects Versions: 3.9.1
> Reporter: Filip Pitak
> Priority: Critical
>
> After an upgrade of maven from v3.3.9 to v3.9.1 the deployment of artifacts
> to a remote repository via _*'mvn deploy'*_ has been substantially slowed
> down. Disregarding the time for installing and other steps, the deployment of
> artifacts went from +-40seconds to 6minutes. As our projects consists of
> multiple modules, the total time of deployment jumped from 20minutes to
> 1h20min. For our remote repository we are using Sonatype Nexus RepositoryOSS
> 3.56.0-01.
> In the newer version maven has switched from Wagon to using "native HTTP",
> which caused this issue.
> I've solved the problem by calling _*"mvn deploy
> -Dmaven.resolver.transport=wagon"*_ and also downgrading the version of
> Wagon. Various versions of Wagon had a different result in upload speeds:
>
> ||Wagon version||Deploy speed||
> |2.7|25 sec.|
> |2.10|35 sec|
> |3.x.x|4 min.|
>
> This solution is not viable in the long-run as it requires using an ancient
> transport resolver and downgrading the version, which is not future-proof. A
> similar solution of speeding up the deployment should be available when using
> the default {*}{{maven-resolver-transport-http}} aka _native HTTP_
> transport{*}. Is there an existing implementation, which {*}{{*}}could be
> used here?
