I want to POST data from Postman Google Chrome extension.
I want to make 10 requests with different data and it should be at the same time.
I guess there's no such feature in postman as to run concurrent tests.
If i were you i would consider Apache jMeter which is used exactly for such scenarios.
Regarding Postman, the only thing that could more or less meet your needs is - Postman Runner. There you can specify the details:
The runs won't be concurrent, only consecutive.
Hope that helps. But do consider jMeter (you'll love it).
