> Talking numbers, D was taking 1.24s to compile its complete standard library in 2010, (too lazy to try out the latest version) including the piles of template code that it has.

I followed in the instructions for building Phobos on the wiki here at https://wiki.dlang.org/Building_under_Posix:

    real	0m12.269s
    user	0m12.896s
    sys	        0m2.150s

Quite a lot of that time appears to be spent linking. I wonder if the post on the mailing list was reporting the literal compile time, rather than the build time?

It was a bit difficult to find a go project of similar size that was easy to build. The backend component of limetext is about 10k LOC compared to 35k for Phobos. When I do a ‘time go build -o foo’ in go/src/github.com/limetext/backend, I get the following:

    real	0m0.163s
    user	0m0.140s
    sys	0m0.207s

Multiply that by 3 plus a bit to compensate for the LOC difference, and it's still pretty good.

Still no idea what you are on getting with regard to CLU. We don't have any info on how fast it compiled.
