Subject Simulating QoS and Speed
Date Mon, 09 Mar 2009 16:27:08 GMT
Hi All,

I've been asked to simulate real traffic for our system using JMeter in relation 
to file uploads in terms of Quality of Service (approx 60%) and realistic 
upload speeds. 

Quality of Service seems reasonably possible with JMeter as its a matter of 
structuring samplers under a number of random and/or throughput controllers.

Simulating realistic upload speeds seems much harder. I'm told that clients 
will upload files to our server at approx 5 - 20 kbps, and to simaulte this 
correctly, I'll need to throttle the connection the sampler makes, rather than 
adding a delay timer. Is there a way to simulate this in JMeter? Nothing jumps 
out at me and I don't recall seeing anything in the User Manual to achieve 
this. Has anyone else had to deal with this situation? Does anyone have any 
thoughts on how this could be achieved?

Regards,
Noel
