Linux - run the same URL parallelly using curl

Below command will run the URL https://your-website-url/path 150 times parallelly with post data. In the below example, I have just added one dummy query string.

curl --header "Content-Type: application/json" --parallel --parallel-max 150 --request POST --data '{"param":"value"}'  https://your-website-url/path?dummy=[1-150]

It is working for GET method as well. If you have other query strings in your URL, assign the sequence to a throwaway variable.

curl http://www.myurl.com/?myVar=111&dummy=[1-20]

I hope it helps.
