How I generated 2000 parallel requests using nu-shell

At work, I need to load test new framework I had deployed.

Usually, I work with QA team. They use JMeter (with Azure Load test) for such task.

But today, the QA person was busy with other tasks, and I didn’t want to get blocked.

Since I am learning rust, (nu-shell is built in rust) I remembered that it may be possible to run parallel requests in nu-shell.

and it is!

The important feature is par-each ¹ which executes the command parallely.

http ² is built-in command for HTTP operations
