I've sent PR to include D benchmark (vibe.d).
I was hoping it could show performance at least not worse than
other languages.
But it appears to be slower than Go and even Node.js
Are there any tips to achieve better performance in this test?
Under windows, I can get vibe.d configured to use libevent to
show results comparable with Go. With other configurations, it
works two times slower.
Under linux, vibe.d shows 45K requests/seconds, and Go - 50K.
The only advantage of D here is CPU load - 90% vs 120% in Go.
I'm using DMD. Probably, ldc could speed up it a bit.
Probably, it's caused by single threaded async implementation
while other languages are using parallel handling of requests?
Its a bit uneven benchmark as you are testing default Go vs
default D + Vibe.D.
One can use a more faster framework like Go's Gin
https://github.com/gin-gonic/gin
In my tests in the past with Vibe.D 0.8, Go was faster with the
alternative frameworks.
