The associated travis CI run that finally went green with ldc 0.16.0 beta 2 took about as long as the other D compilers, so performance of ldc-compiled ddmd seems comparable:

That's surprising given that many were worried that switching to ddmd would slow compilation speeds down by at least 30%. Also, this does not seem to be using any of ldc's optimization flags.

Well, all three of those are ddmd: the only difference is whether ddmd is compiled by dmd, gdc, or ldc. The 30% measurement was based on comparing the previously completely C++ dmd with ddmd:
