'''To run the static content load test, make sure you've bootstrapped your

test environment and set up your config.yaml file, then run the following:
|
|
S3TEST_CONF=config.yaml virtualenv/bin/python generate_objects.py -O urls.txt --seed 1234
|
|
|
|
This creates a bucket with your S3 credentials (from config.yaml) and
|
|
fills it with garbage objects as described in generate_objects.conf.
|
|
It writes a list of URLS to those objects to ./urls.txt.
|
|
|
|
Once you have objcts in your bucket, run the siege benchmarking program:
|
|
siege --rc ./siege.conf -r 5
|
|
|
|
This tells siege to read the ./siege.conf config file which tells it to
|
|
use the urls in ./urls.txt and log to ./siege.log. It hits each url in
|
|
urls.txt 5 times (-r flag).
|
|
|
|
Results are printed to the terminal and written in CSV format to
|
|
./siege.log
