# By default, this script will run 15 tests generating sequentially more load
# by adding 1 parallel worker per test number.
# The 1st test will generate 1 worker, the 2nd test 2 parallel workers,
# up to 15 parallel workers.  Each parallel worker will generate
# 500,000 requests.
# For additional load, total_tests can be increased to add more testing
# iterations, or parallel_workers_multiplier can be increased to run more
# parallel workers per iteration. For example, parallel_workers_multiplier=5
# will result in 5x parallel workers per testing iteration.
# The output for each testing iteration will be located in logs/test#.log

# URL of the beacon servers: http://ALB-DNS-NAME/beacon

export requests_per_worker=500000

export total_tests=15
# Multiplier for the number of parallel workers per test
export parallel_workers_multiplier=1
# Delay between requests in seconds (e.g. 0.1 = 100ms)
