As of today, when given an option, I will choose Go over Scala anyday. The code speaks for itself. But out of curiosity, I took a look at memory and cpu requirements... (screenshots below are from the 'top' command).
VIRT stands for the virtual size of a process. In a nutshell we are talking about the sum of memory it is actually using (memory it has mapped into itself, shared libraries, and memory shared with other processes). VIRT represents how much memory the program is able to access at the present moment.
RES stands for the resident size, which is an accurate representation of how much actual physical memory a process is consuming. (This also corresponds directly to the %MEM column.)
Scala uses 74MB of RAM (RES), but 297MB for VIRT.
Go, as expected, uses only 5.4MB of RAM (UPDATE: to be honest, it's more like 3.8MB), but has mapped 828MB (VIRT). This I didn't expect.
Anyhow... it was fun while it lasted. The awesome part is knowing how much more RAM I got freed up on my box after this exercise. ;)
