how to test 50k users in laravel application

You can use factories

thanks bro but i didnt get it how can it be possible to test whole application , is it like this to make factories for every single model and run them like 50k times ??

What exactly do you want to test?

An average response time of some requests when you have 50k records is the database? In that case you should fill your database with records anyway.

Do you want to test it locally or in production? On real server?

when my application Hosts 50k users it gets slow i want to find the bottle necks and fix them to increase the capacity to like 100k and thats it i want to see which part has problem i am sorry if ive not been clear enough :)

Here Rasmus Lerdorf talks about PHPSPY. I did not work with it, but maybe it is what you want?

@martal i will check it out on my project thanks for the guide
