It might be nice to enable DMD in our b2g eng builds. I've been running with DMD on my test device for a few weeks and I have not noticed any significant performance impact. One issue I am unsure of, however, is how to provide symbols for a DMD report generated from a releng spun eng build. Locally I have to tell get_about_memory.py where my objdir is. Do we have a way to do this for releng builds?
There is a moderate but definite performance hit when DMD is running. I know this because at times I have run DMD on my normal desktop browsing sessions; I gave up because the slow-down was noticeable and actively annoying me. This idea has come up before, but I don't think it's tenable. Though I'm not sure exactly what a "b2g eng build" is.

I believe an eng build basically builds with: ENABLE_MARIONETTE=1 ENABLE_TESTS=1 Anyway, if there are known performance issues on desktop lets just not do this.
