My times were all single threaded. Comparing parallel builds on a 
shared server with varying loads is kind of pointless as the 
build are all over the place and can not be used to draw some 
conclusion.
Furthermore, I avoid parallel builds as there are often problems 
with them. My first build of clang+llvm that I had done with -j 
option was a catastrophe, it grabbed all the cpus and hogged the 
machine for a long time and failed to build properly. Only when 
limiting to -j 4 was I able to build it and even then it took a 
little less than an hour.
The nice thing with dmd is that you can build it gently in single 
task and it doesn't take you a whole morning to get it set up.

PS: The environment we work on at work are very restricted for 
security reasons, this means that the servers are built from 
standard images provided by IT and any piece of software that we 
want to install has to be built from source. The standard image 
has gcc 4.4.7 installed, has no graphic libraries (X or 
whatever). Even git has to be built from source.
