I don't have the psutil module and I'm not versed in python but I ran lscpu:

> override heap / jvm params for tests in gradle build
> ----------------------------------------------------

> Key: LUCENE-9160
> URL: https://issues.apache.org/jira/browse/LUCENE-9160
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Robert Muir
> Priority: Major
> Fix For: master (9.0)
>
> Attachments: LUCENE-9160.patch, LUCENE-9160.patch
>
>
> Currently the gradle.properties that is generated lets you control the heap
> and flags for the gradle build jvms.
> But there is no way to control these flags for the actual forked VMs running
> the unit tests. For example, minHeap is hardcoded at 256m and maxHeap at
> 512m.
> I would like to change minHeap to 512m as well, for a fixed heap, and set
> some other jvm flags, such as {{-XX:+UseParallelGC}} so that my tests are not
> slow for silly reasons :)
> I think it is stuff jenkins CI would need as well.
