[GitHub] [maven-mvnd] conderls commented on issue #388: Have mvnd run for some popular Maven projects to show performance improvements

URL: https://github.com/apache/maven-mvnd/issues/388#issuecomment-1280504986
I did an experiments in a multi-module projects(43 sub-modules, sorry for not able to provide the internal code) on a machine with 128 cores, with build command:
`mvnd -pl $MODULES -am spotless:apply clean --no-snapshot-updates install`
vs
`mvn -T 1C -pl $MODULES -am spotless:apply clean --no-snapshot-updates install`
scala: 2.12.12
mvn: v3.6.0, ~ 03:49min
mvnd: v0.8.2, ~ 03:50min
**NO** performance improvements found, though the output looks much better just during building project(it seems that the stdout output is almost same, which is just rendered by `mvnd` during build, i.e. non-rolling view).
considering building uber-jar with maven-shade-plugin:3.4.0, the performance bottleneck maybe the conflicts check and copy deps during assemble stage (offline-all)
