Http4kLoom

Super simple test to check Http4k with Loom

How to start

You need a Jvm19 or later. Either configure IntelliJ to run on language level 19-preview and run Main or use gradle from command line:

./gradlew run

and in another terminal launch some performance tool like autocannon:

autocannon -c 10000 -d 10 localhost:9000?name=ubi

Results

Vanilla Http4k-jetty:

Average 981 req/s with 100ms sleep and 100 connections Average 1700 req/s with 100ms sleep and 10000 connections

Loom enabled Http4k-jetty:

Average 980 req/s with 100ms sleep and 100 connections Average 80k req/s with 100ms sleep and 10000 connections

So 40x performance increase... not bad.
