Hi guys,

In my journey of learning about D I tried to benchmark D with Vibe.d vs node with express and Ruby with Sinatra.

And the results are pretty surprising.
I have to admit that I though D was more faster than that. How is this even possible ?

I am doing something wrong ?


Here are the numbers with the project :

Probably node and Ruby cache PGSQL connection - keeping it open.

Okay I'll manage to do it, but still the req/sec are pretty low ...

You should know: https://www.techempower.com/benchmarks/#section=data-r12&hw=peak&test=json&l=ft4

Dlang is quite slow. I have no idea way, or how to improve it. But clear, is not that fast. Maybe for web related is slow.
I'm more curious about more benchmarks :)

oooh, I wanna try my libs.

Where's your database dump?

The postgres library (dpq) that you're using doesn't use the event loop that vibe-d provides. Every call you are doing is blocking the whole server. Of course this is going to be slow.
You can try using http://code.dlang.org/packages/vibe-d-postgresql.

So, the benchmark, the Ruby, and the JS all use the path to be /.... the D seems to use /companies (though I don't know vibe). Is that right?

Yes it's that i'm routing to /companies to get the result, but let me change the psql library delete this routing and trying again.

All right after switching of psql client I had lower results actually ...

Req/Sec 22.85 for 30 seconds.

What are you using to do web if you don't user Vibe.d?
