From the paper, "in order to understand how many unikernel VMs we could pack on a single server when RAM is a bottleneck, we ran experiments to measure the minimum amount of memory required to boot various applications as unikernels, finding that 2-6MBs of memory suffice for Unikraft guests."
Run instructions:
./genimages.shdownloads and builds the tested images anm takes about 2m on average;./benchmark.shruns the experiment and takes about 6m30s in average; and./plot.pyis used to generate the figure.
