Looks like gist still doesn't support pull-requests. These changes were helpful to me, maybe you could add them too?

Without /dev/null, it would output html sporadically.

Cheers!

Nice script, small tip : add trap "kill 0" SIGINT at the top to make sure that all curl requests are killed off if you cancel the stress test

Created a custom version that accepts different http methods and body request https://github.com/rodrigorodrigues/quarkus-vs-springboot-reactive-rest-api/blob/master/naive-stress-test.sh

./naive-stress-test.sh -c 1 -r 1 \
-a localhost:8080/api/companies \
-X POST \
-H "Authorization: bearer XXXX" \
-H "Content-Type: application/json" \
-d '{"name": "test curl - #INCREMENT_TIMESTAMP", "activated": true}'

Cheers
