Michael Osipov commented on MPMD-413:
-------------------------------------
I raised the same in a recent PMD issue:
https://github.com/pmd/pmd/issues/5293#issuecomment-2441879376
> Add support for configuring the max number of threads to use
> ------------------------------------------------------------
>
> Key: MPMD-413
> URL: https://issues.apache.org/jira/browse/MPMD-413
> Project: Maven PMD Plugin
> Issue Type: Improvement
> Reporter: Joseph Leonard
> Priority: Major
>
> h2. Background
> Currently it doesn't seem to be possible to configure the number of threads
> that the plugin should utilise and therefore it [defaults to the number of
> available
> processors|https://github.com/pmd/pmd/blob/main/pmd-core/src/main/java/net/sourceforge/pmd/PMDConfiguration.java#L100C7-L100C70].
> This can be impactful if you don't wish to allow the plugin to make use of
> all your processors. In our scenario this is particularly impactful because
> we are running a heavily parallelised multi-project monobuild and therefore
> we don't want each parallel module build to attempt use the same number of
> threads as available processors.
> h2. Improvement request
> It would be nice if we could add the ability to configure the number of
> threads via the plugin.
