locust load testing appropiate Number of users to simulate and hatch rate

Question

I am doing load testing using locust. I write a script and set up everything for load testing.

Only two points I do not understand actually,

What is the meaning of the below numbers? e.g

Number of total users to simulate
Hatch rate (users spawned/second)

What will be the appropriate value for these two options?

The number of users: the number of users testing your application. Each user opens a TCP connection to your application and tests it.
Hatch rate: For each second, how many users will be added to the current users until the total amount of users. Each hatch Locust calls the on_start function if you have.

for example:

Number of users: 1000
Hatch rate: 10

Each second 10 users added to current users starting from 0 so in 100 seconds you will have 1000 users. When it reaches to the number of users, the statistic will be reset.

So, is it like after resetting it will start hitting request again? – Dhruvil Amin Jan 11 '19 at 06:02
@user3260373 yes until you stop it. – Mesut GUNES Jan 11 '19 at 06:13
Is there a way to control the rate of requests per user? or is that always done in a blocking fashion? – Austin Oct 16 '19 at 21:17
It tries to distribute the load equally for each user. Instead, you can give weight for the tasks, not the users. – Mesut GUNES Oct 17 '19 at 08:46
