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?
Doesn't vibe-d use Fibers?
I tried to build a simple web server with a fiber-based approach
once - it was horribly slow.
I hope C# (and soon C++) style stackless resumable functions will
eventually come to D.
