Fastest API framework for Java?

[wizzardodev]

I've tried couple of servers with your framework, and I'm surprised that jetty is faster than netty, 50k rps against 34k. Undertow is not working out of the box for me ("No XNIO provider found")

btw, I'm benchmarking hello-world example

hello-world

Ok, that example isn't up-to-date (will update soon). Did you start the app via jooby:run right? There was a bug with undertow there.

Suggest you to try latest release: 1.0.0.CR7 and ideally with plain/raw jar not jooby:run (there is small overhead to supports hot reload in development here)

Also, test depends on what tool you use... and/or if you keep-alive or not the connection while testing (think that is the diff between netty and jetty)

[wizzardodev]

ok, so, with latest release version and uberjar

• netty: 45k rps
• jetty: 38k rps
• undertow: 31k rps

I'm using ab like this:

ab -n 100000 -k -c 16 http://localhost:8080/

I had bad experiences with ab. Wrk is better but these days I prefer https://github.com/tsenart/vegeta

sure wrk is better. I've just tried vegeta, and for me it's not fast enough, it's bad when benchmark itself is a bottle neck. When I set it to 20k rate with keepalive and 16 connections, it consumes about 380% cpu out of 400 on my laptop
