I have a PHP web application, and I want to test out the load when 100+ users are connected at the same time. Is there a program out there that would allow 100+ virtual users to hit my webpage?
I did find one, but it was $3000. I don't mind paying, but not quite that much.
You can do this easily with JMeter, which is open source.
100+ users each requiring how much memory? You might need several machines to accommodate the desired load, but it's certainly doable.
Apache Bench is free, and runs on all flavors of *nix:
ab [ -b windowsize ] [ -c concurrency ] [ -C cookie-name=value ] [
-n requests ] http://www.example.com/page-to-test.html
Try:
man ab
I've found it works great when you just want to make sure you can handle a certain load.
For more complex load-balancing, spend the money.
You many need something more advanced, but a first approach may be suited for Http_load http://www.acme.com/software/http_load/
It is a basic script that spins up a bunch of threads and hits your website for a specified duration. It reports back with some interesting statistics related to throughput and the number of successful responses.
