Simply running a "hello world.exe" takes, on my pc:
1.12s When compiled with dmd
0.62s When compiled with ldc
0.05s When compiled with dmc (C program) or dmd/ldc as a -betterC
program
I suppose initializing the runtime takes a lot of time. When
making a simple command line utility, half a sec

This is not concerning for large applications indeed. But say, I
want to implement my own `dir` (= `ls` on Unix) in D. Woul

Are there ways to reduce this to below 0.1s, or should I just
leave idiomatic D and make a betterC program?
The best solution would be to profile the startup process and
file a bug accordingly. ;)

I suspect you are seeing the Windows antivirus hitting you. D
runtime starts up in a tiny fraction of a second, you shouldn't
be noticing it.
