3GB is likely enough if nothing else is going on and you're not
presenting more than one virtual CPU.  With two CPUs and other builds
going on, you're likely swapping which is going to hurt even more in a
vm.  You might consider turning off OPTIONS you don't need beyond doc
(in particular LLDB is large and hard for our ancient linker to link).

P.S. build time on a lightly loaded 24-core machine with SSD and 256GB
of RAM exceeds 10 minutes and performs several GB of disk IO so taking
more than a day seems long, but not completely implausible on your
system.
