Conclusion
Because the default capacity of a VSphere Standard Virtual Switch (VSS) is specified as 200kpps, we must conclude that vSTREAM-STL Stream to Disk performance is hardly affected by the number of CPU and memory assigned to the virtual machine.
We did experience instability issues whenever the memory size was not in line with the numer of virtual CPU. You must provide 2GB of RAM per vCPU. This is also a recommendation of VMware itself.
