# We use this script to simulate the login of multiple concurrent users, with
# one login per second.
#
# To use it, you need:
# -ruby
# -pre-created users
#
# This can be run with `ruby blocking_spawner <x>`
# where x is the number of users you want to login.
#
# It was created to measure login times internally on the application with
# varying number of users
