About compiler memory consumption

[Puming]

Hi, I'm learning D, and trying to develop a website using vibe.d.

I'm using Digital Ocean's VPS server, with 1GB memory. Many a 
time when I do `dub`, the memory consumption soars and forces dmd 
to quit, sometimes even causes the remote machine droplet to 
freeze.

I understand that due to template and static analysis in the 
compiler, the memory usage is huge for template heavy code. But I 
heard that there was effort going on and progress is already made 
in recent releases.

My question is, is there a plan for this effort? What is the 
general prediction of an ideal D compiler, some hundreds of MBs 
or less? I'd like to switch to 512MB VPS droplet, as it's much 
cheaper. When (which release) would the memory cost be in 
reasonable level?

As an alternative, I can build the project locally and rsync the 
binaries to the VPS, but a simple binary in vibe.d yields a ~12MB 
file, it's somewhat slow to upload it. So I wonder can we refer 
vibe.d/phobos as a dynamic library?

Thanks,
Puming.
