Have you compared the Locust with the Tsung?

I have compared them ,and the result is Tsung is more better. Especially in RPS. PS. the test environment is the same. 32G mem and 8 CPUS.

Hardware is cheap compared to developer time. Locust's goal is to be able to simulate real user behaviour by writing python code (and not XML), and then simulating lots of these users using the system. "Recording" sessions doesn't always cut it.

If Tsung solves your use-case in a better way than Locust, I recommend that you use it.

thx.
one more question, why do you choose the requests, pycurl maybe is better than this.

[heyman]

Because requests provides the best API. It's quite simple to use some other client lib with Locust if one wants to (see http://docs.locust.io/en/latest/testing-other-systems.html).
