Erlang: Pi2 ARM Cluster vs. Xeon VM
Keep in mind that this Xeon (E5620) was released in 2010, whereas the Cortex A7-Quad seems to be from 2015? So it would be interesting to compare the ARM cluster against a comparably new Intel CPU (say Haswell or Broadwell); in my experience, even a mid-range notebook CPU (i5-5500U) from last year easily outperforms Xeons (E5-2650) even from 2012.
