Hmm, the make file already has 2GB per process set up.

https://git.ipfire.org/?p=3Dipfire-2.x.git;a=3Dblob;f=3Dlfs/dnsdist;h=3D9f204=
0f16583e033f624e24415953396a4d9e526;hb=3DHEAD#l40

So it will launch one compiler process per 2GB of memory. Obviously less than=
 one isn=E2=80=99t possible.

You can try filtering out =E2=80=9C-pipe=E2=80=9D from the CFLAGS and CXXFLAG=
S, so that the assembler will be stared after the compiler is done and not in=
 parallel. That will also save a couple of megabytes, but probably not a mass=
ive lot.

In general I can recommend to add more memory to your build system. 4GB seems=
 to be a bit of a sweet spot. More than that normally does not make any diffe=
rence.

Best,
-Michael
