dmd, vibe.d RAM usage when compiling.

[SrMordred via Digitalmars-d-learn]

I never notice this before, but i tried to put a basic hello 
world from vibe.d (like the one that are in the dlang front page 
examples now), into the most basic instance on google cloud (with 
600mb of RAM) and the compilation returned
"Killed
dmd failed with exit code 137."

So I look at the RAM usage and saw that when compiling (with dub) 
it uses 550mb+.

So i´m unable to put hello world to work.

Aren´t this number a bit too high for a basic example?
