Most of the modern systems have more than 1 cpu or core. Most of the modern make's support parallel builds: gmake -j [N] or --jobs [N], dmake -j NumberOfJobs. The request is to set default parameters of makes to parallel mode when used form IDE. It may be done through toolchain personality.
*** Issue 138945 has been marked as a duplicate of this issue. ***
The generated makes are dmake compatible but the problem is dmake defaults to parallel mode by default so you won't see the benefit if you havent defined dmake options in the .dmake setup file or as environment variable.
