It should be fairly easy to enhance the code to calculate an additional delay per request.
Would that solve your problem? S. On 07/11/06, Christensen, Alan <[EMAIL PROTECTED]> wrote:
Hi Sebb- I was afraid that that the "characters per second" mechanism for simulating slow bandwidth links was the only thing available. Although this mechanism does probably work by inserting delays, it really doesn't properly simulate network latency. The actual delay in response time that would be incurred for a transaction using the cps mechanism would be directly proportional to filesize and nothing else. The proper delay incurred for network latency effects would be dependent upon the actual number of serialized request/reply or acknowledgement cycles that occurred during a particular transaction. For example, a user in Australia with 400ms of round trip network latency to a server in Texas would incur at least one 400ms latency penalty in downloading a page. This latency penalty would be independent of the users "last mile" bandwidth. A user in Texas with 30ms of network latency would incur at least one 30ms latency. The number of latencies that worldwide users would incur would be the same for a particular transaction, but the number might be different for different transactions. I don't want to analyze each transaction to see how many latencies are incurred for each one, so I wanted to simulate this effect in jmeter. Unfortunately it sounds like there isn't a built in mechanism to do so.

If you use the HTTPClient HTTP Sampler, you can set up the connection to behave like a slow modem - see the comments in jmeter.properties. S.
