[SciPy-User] Simulate web requests

Hi,
       Good article. I was earlier planning to use PDQ for this.

Actually I was trying to use a statistical library to hit by web url in such a way that certain distributions of these hits can be simulated. It looks like SciPY code could be used to do that. I use basic R but when I want to simulate traffic like this I use java. It looked like SciPY can help write such code. It is a web statistical traffic simulation test for measuring and modeling for capacity planning.

I will queues also to simulate but that is a different form of simulation ?

Thanks,
Mohan

Hi Mohan,

You might consider using simpy for the simulations. Here you can also
find a simple, straightforward, simulation of a generic single-server
queue: http://nicky.vanforeest.com/queueing/simulateQueuingProcess/queue.html.
It should not be too hard to modify to a multi (infinite?) server
queue.
