SQL Server is designed to scale across the spectrum of small machines to enterprise class servers. The changes made in SQL Server 2017 CU4 improve resource usage on smaller machines, such as a VM or Container used for testing and development. For SQL Server 2017 CU4 the small environment threshold is 2GB.

Prior to SQL Server 2016 the trace flag –T8048 is used to upgrade (only) NUMA partitioned, CMemThread objects to CPU partitioned based objects.

In fact, I was able to break the reproduction down to a single connection using an idle SQL Server so there was no impact from other workloads. Powershell Script.
