I'm creating a patch for a bug in bitcoind code, and I'm compiling bitcoind on a Ubuntu virtual machine with 1 GB of RAM and 1 core.

What can I do to speed up compilation?
Will adding an additional core decrease compilation time? Does it benefit from "make -j 2"?
Will adding more RAM decrease it?

Adding jobs only helps if you have more cores indeed. It only slows you down if you add jobs and have only 1 core.

Make sure you have ccache installed (and that it's being used).

It will speedup with make -j2, but on a host with only 1gb of ram probably not because you'll just end up swapping.

If you do not require bitcoin-qt, use the option
./configure --with-gui=no
to skip compiling that.

but using use the option ./configure --with-gui=no i compile in Deamon mode?

More ram will likely help (actually, I'm somewhat surprised that you're able to compile it with 1GB ram, I assume you have swap too). Yes, it will benefit from -j2 if your VM has multiple cores. Also make sure you have ccache installed... that will speed up subsequent compilations.
