D can be arbitrarily slow due to its meta programming features. The comparable feature for Go would be some code generation integrated into the build process. This difference makes it hard to compare.

For simple (non-meta-programming) code. Dmd and Go are in the same league with respect to compilation speed.

Btw compilation speed is the main reason for me to put off Rust and C++ and Scala. I cannot stand slow compilers anymore after using D for a while.
