This one of the main strengths of D, it is what Walter focuses
on, yet I have seen almost nothing on the D blog talking about
this. What brought me to emphasize this today is this recent
post about how long it takes to compile the mostly-C++ Chromium
web browser and the reddit discussion about it:

https://www.reddit.com/r/programming/comments/7ktzog/chromium_has_a_compilation_time_problem/
I'm tempted to call BS on that 6-7 hour build time, as I used
to contribute to the Chromium project, and I think it used to
take me 20 minutes for a release build in a FreeBSD jail on a
fairly weak, 2008-vintage mini-desktop, a dual-core Celeron
with 2 GBs of RAM (don't hold me to that build time, just a
vague recollection, but probably in the ballpark). Of course,
the last time I built Chromium was more than 5 years ago, and a
lot has likely changed since then, such as now using LTO to
speed up the browser apparently, and maybe the
cross-compilation toolchain for ARM is slower, though others
note similar times for native x64 compilation also.
That still implies a slowdown of 2-3 orders of magnitude over
the last 5 years, given the much more powerful hardware he's
using, which is nuts.
D really needs the community to write blog posts talking about
how fast it is, publicizing that there is an alternative to
these glacial build times: who wants to do this? It doesn't
need to be on the D blog, could just be on your personal blog,
but it is a message that really needs to be spread.
D does not do itself any favors when it keeps accepting mediocre
results in benchmarks.

Some years it does not complete the tests, in others it shows
results that are below mediocre.
Vibe.d ( and other D web frameworks ) benching twice slower then
scripting languages like PHP/Ruby. That does not advertise D.
How about:
http://benchmarksgame.alioth.debian.org/
No D there? Performance must be bad because its not listed at all
( for a language that exist 20 years )?
Another one:

Single threaded ( look at CPU total ), losing to other languages
again.
Impressions are everything when there is a wealth of languages to
pick from. Anybody stumbling over these results think: Well, i am
better going with Go, Rust, Crystal, ... for a web hosting as
they show more consistent high speed results.
