Conclusion
Because the unofficial default capacity of a VSphere Standard Virtual Switch (VSS) is considered to be around 250kpps, we must conclude that vSTREAM-STL Stream to Disk capabilities are hardly affected by the number of CPU and memory assigned to the virtual machine.
The 5' results show a high variation over time at 1488kpps (almost 500% of the assumed capacity of the VSS) is exeeded.
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.
