Scott Wegner commented on BEAM-4122:
------------------------------------
I've asked in INFRA-16380 about machine specs and performance characteristics
of the build. Once I hear back I'll work on tuning Gradle's parameters.
Probably the main option to tune is the number of Gradle workers. I believe
Gradle allocates workers according to number of CPU cores, and each one has 1GB
or memory space.
> Tune Gradle resource usage on Jenkins

> Project: Beam
> Issue Type: Sub-task
> Components: build-system
> Reporter: Scott Wegner
> Assignee: Scott Wegner
> Priority: Major
>
> The new Gradle build seems to be exhausting memory on the Jenkins machines,
> causing them to lose their connection and die. This has made our tests
> extremely flaky.
> We need to tune the Gradle build such that it does not exhaust Jenkins
> machine resources.
